Sounds swole. I don't recall using the ability much, so it seems like I totally missed out.

I prefer Warp Ammo for my bonus power. Even when playing Soldier because it's vastly superior to Inferno Ammo, so I level WA instead of IA. On Insanity EVERYONE has some type of protection. Since WA is great against armor AND barriers, it's a great choice for Insanity. It also weakens armor, and you get big damage bonuses against lifted targets. That last point is a big bonus when you're playing as an Adept like you are.

Yeah a Soldier is quite hard in case of choosing a BP .... if you want to stick to the class, then Biotics should be a no go... leaving you with defence stuff, Energy drain or an Ammo Power.

If Warp Ammo is your preference, thats fine for you. Everyone's his own preferences, as it suits the personal playstyle and that is great. I am no eltist jerk, furthermore have there been discussions about the best talent evolutions and ammo powers since the beginning of the game. Simple Fact Warp Ammo is far better on slower, hard hitting Weapons and can save you from the need to take a piercing mod.... while Inferno Ammo is only with the Explosive Burst Evolution and on rapid firing weapons most effective and depending on your playstyle and squadbuild can outmatch Warp ammo, as the damage bonus is limited to the base damage of the single shot/bullet of the weapon, while the explosion gives plain 100 dmg per ignition.

e.g. I just finished Cronos Station on my playthrough and James melted the Atlases in 3 seconds (shields were stripped by EDI and me)..... with Explosive Burst Incendiary Ammo and his Particle Rifle......

But as stated befor never change a winning team.

I also found out that i could not execute a biotic explosion via my warp if i primed the target with my own warp. So you need to take a squadmate or a different power to excecute it. On the other hand Stasis can even replace the usual recommended Energy Drain for the Adept, as the Stasis holds and primes a target for a biotic explosion, even if it is shielded.

After finishing this particular playthrough I'd like to summarize:

Marksman is a nice Bonus Power if you want to play ME3 more like the ME1 style.

Though it does increase the effectiveness of hardhitting slow rof weapons, it excels beeing used in conjunction with rapid firing weapons and Incendiary Ammo with the Explosive Burst Evolution.

Edit:

The bigger the Clip, the more useful it becomes, as you would otherwise loose precious time during the reload sequence. This lets the Tempest outperform the Locust for example, as both are almost same accurate with Marksman but the Tempest has to reload less due to the bigger clip.

Soldier and Infiltrator has no use of it as Marksman prevents any other power to be used during it's duration.... so keep in mind it's either gunning or power spamming.

For a Vanguard it can become a situational benefit, when Charge is not an option.

It does increase your DPS because you simply dash out double the shots in the same time. Your clip gets emptier in at the same rate aswell so watch out. And your Weapons (high recoil like the Revenant or widespread Shotguns) are far more accurate (unfortunately not the aiming circle), especially on midrange.

Although I ran through Priority Earth with a Lancer V and Squad Warp Ammo (Liara and Tali in group) it was more running than gunning while fighting the Banshees. IT took me 80 rounds to down the Armor of a Banshee this way and I never used that much medigel before.

Conclusion: It is an interesting Bonus Power that might has been overlooked but can be fun, if you can adapt it to your playstyle, or your playstyle to the power.

Agreed, well mostly lol, but since he's an adept the extra lifted target damage bonus of WA is huge. It's double damage(+100%) if you level it as such. Plus Inferno Ammo does not weaken armor like WA, and it does nothing to barriers whereas WA actually does more damage to Barriers than armor/health. I disagree with your assessment of WA being better for slower firing weapons. I don't think the rate of fire/base damage really matters in terms of your ammo power choice. They do what they do, and they do it every shot you fire regardless of which power you choose. Take WA with 50% armor weakening evolution, go to town on those Atlases after their shields are down, and see if they don't fall at least as quickly as they did with the IA/burst evolution. I'd wager faster tbh. I suspect it would rival the IA even at 25% weakening. I think it's more about your other point....your personal choice of play style. To each their own for sure.

Definitely.

That Atlas example just shows that your squadmates handle charging weapon differently and the Particle Rifle with IA is way too overpowered as they instantly gain the highest rof and therefore more chances of proccing the Explosive Burst (which is 50% procc chance per Round).

What I meant with the hard hitters was, 70 % damage increase on a shot that does 1000 damage per round with an rof of 1round per 2 sec is way more effective than on a rapid firing gun that does 50 dmg per round with 4 rounds per sec.

But maths and personal experience sometimes go separate ways.
