If you browse various forums, including the Bioware ones, you will see many people state how Adept has the hardest time on Insanity mode, the main reason being the fact all enemies have some kind of protection that prevents biotic abilities from being effective. Yet, is this true?
Simply put, no. There is only one thing that Adepts can’t take care of on their own innatively, and that is shields. However they handle care of everything else. Warp is a very powerful skill, which is at the core of the Adept class; it detonates existing biotic effects on enemies for added AOE damage, it stops health regeneration, it’s effective against armour and biotic barriers. The Adept is better equipped than the Vanguard and the Engineer at ripping off things that stand between your skills and the enemies’ health bar.
So why all this fuss about Adept being the hardest class to play in Mass Effect 2 on Insanity? It’s simply due to wrong assumptions. Just because you can’t use Pull or Shockwave on something straight away, it doesn’t mean you are not being effective. Warp does a ton of damage and using it a lot is being an efficient Adept. Having one companion with Overload or using Energy Drain as your Advanced Training skill will solve any issue with shields. Shields will go down in the blink of an eye as soon as you get some upgrades, and you will find yourself AOE pulling and Warping away through enemies faster than you ever imagined.
I found Adept competes with a well upgraded Vanguard in terms of killing speed. You can storm through any mission, or at least handle them without much issues. My two videos below will show you just how effective an Adept can be.
This first video is from Mordin’s Recruitment mission. All enemies posses armour. The common biotic chain I use there is Warp (Miranda’s or mine) > Jacob’s Pull > detonate with the other Warp (from whoever hasn’t used it yet). That’s it. No need for snipers to get the Vorcha on the opposite side on bridges, Pull and Warp take care of it.
The second video is Tali’s Recruitment mission. I chose this specifically because it was full of synthetics with shields, which are supposed to be the hardest enemies to kill for an Adept. I pretty much stormed through the whole thing, and I hope this video will change your mind about this class. I used Energy Drain, which lowers the enemies’ shields and restores your own. Even when Miranda died at some point and I had no Overload, I took care of shields with no fuss.
