Great strategy for sub-platinum matches. But let's see how that works on Platinum boss spam...
Actually, it works perfectly well on Platinum too. It only needs a "nova cancel" once in a while and a "shoot" once after every action and you're golden.
That is, if you know how sync kills work...
Yup, you just need to adjust and change your playstyle*. Some players keep playing off-host as if they were hosting, so they just bang their heads against a wall and complain that the lag is killing them. Some players adjust, take the lag into account and charge when it makes sense to do so while maintaining a margin of error.
(*: Not always particularly easy to do so, of course.)
Adjusting my playstyle?!?!? NEVAHHHH!!! Imma gonna play the same, go down once a wave and rage gel before I hit the floor. That's the right way to do it, not "changing one's playstyle", for claymore's sake!
... Now that I think of it, this might, or might not, have something to do with me hating lag so much 
I cant stand krogans in general; they're just too slow and too heavy. So for me, probably my favorite is the Batguard. Biotic Charge+Hatesurf is perhaps one of the most fun things ever. You fly in from halfway across the map, send them flying, and follow them into the darkness where all they hear is a loud *Crunch*. Then you disappear again. Or you don't, and you just stand there, tanking all their damage indefinitely.
Otherwise the Cabal is pretty fun, but whoever it was that said F U London...high five. Ugh. London is just AWFUL. You can't dodge ANYWHERE. The magical ability to blink out of existence for a moment and then reappear right back in the way of the missile you were trying to dodge. Yay.
I just wish Poison Strike did a little bit more damage, especially versus armor. As it is, it annihilates all mooks really easily, but bosses are a pain in the plates, at least compared to more dedicated boss-killers like Adepts. Still, the ability to Poison Strike through an entire spawn repeatedly is one of the more fun things you can do in the game. You're just bulldozing your way through 8 enemies, sidestepping sync-kill enemies by inches, and killing them all without taking any damage. So fun.
That was me. I remember when the Cabal was shown on livestream I was so hyped, I thought that would have been the best character ever released, it was just SO mobile. The first thing I did when reckoning hit was play the Cabal exclusively for quite some days. And that is when I slowly discovered all the bullshit that was hidden behind the great appearance: I-frames not working, dodge not working... Such a disappointment. Gah. I'd give anything for them to fix her straight.
