I haven't played ME3 with a Vanguard (only multiplayer) so I'm looking forward to taking this character through to 3. I just wish the game would let you change class on NG+. Having to start all over again on insanity is hard
ME2 Vanguard is tactical and calculated, especially on Insanity difficulty. Every Charge and Shockwave you make has to be carefully placed, and they're more like setups to find the perfect flanking position and drastically change the outcome of a firefight.
They're not the primary attack of the class which you can spam a million miles a minute. If you pick your choice of enemy poorly, you get a one-way ticket to CRITICAL MISSION FAILURE
Compared to ME2, ME3 Vanguard is fuckin' baby gameplay, imo they turned one of the hardest but most rewarding characters into one of the easiest shrug-fests. I've gotten bored of my own Vanguard shep tbh, and I've already switched to my third char (Renegade femshep Soldier + Garrus ship).
I'm actually having more fun shooting things than I am constantly pressing number keys 1 and 2 ad nauseum. Charge-Nova vanguard bores me
that much.
