Adding onto my hatred of those weeaboo Phantoms...apparently they can sync-kill you without meleeing...what the **** Biower. Is there even a point playing as a Vanguard outside of Geth?
inb4 no, because no.
I play Novaguard against Reapers when I have enough Biotic Friends around. Also Slayer VS Reapers. My KroGuard tears Reapers a new one with Fire Explosions. Cabal is good against Reapers too. BatGuard kills everybody, with scumbag level no fks given. Assguard I do use against Geth for level 1 Bronze and Level 5 Silver solos though.
I'll stop now, but yeah, most Vanguards can be quite good against Reapers. Just need to learn the enemy. Seriously, reapers are weaksauce. Just keep moving and they are not the least bit threatening.
