Thing is : I'm already maxing CHARGE + NOVA + SHOCKWAVE. That's the main difference in ME:A's way of playing vanguards (at least the human, haven't tried the others yet), you just don't charge + detonate with nova anymore, it's "the opposite" that's why they allowed to have 3 main skills maxed and make shockwave usable on top of NOVA + CHARGE. It basically goes like this :
CHARGE to ennemy (detonate if already primed), NOVA (primes), SHOCKWAVE (detonate + prime), CHARGE etc... And even with all that, in gold, you just won't kill a single ennemy, which is nuts.
Whereas before, it was basically CHARGE (primes) + NOVA (detonate) rince and repeat. Or go with a different build with SHOCKWAVE, but it was different builds. It just was really brutal and did tons of damage. Now, since you can level up more, I think what they tried to do is compensate that by "diluting" damage outputs, they just overdone it to a ridiculous point. I'm really hoping a big balance patch is coming soon, because all it does is making me want to go play ME3 again. It's a shame, ME3 with the feeling (jetpack and the whole added mobility now) of ANDROMEDA would be so, so good...
