Well now, saw something I very much so like today. Incinerate -> Warp = Fire Combo. Two powers that are individually good anti-armor abilities, now creating the second strongest combo in the game together on top of that. Suddenly Engineers and Adepts (and the Turian Sentinel) make much better partners than they ever did before.
Anyway, three more Premium packs. Still no Geth Engineer, and no Geth Plasma SMG either sadly. However, I got my final rank in the Striker, making it my first maxed-out rare weapon. I do believe my Demolisher will be seeing some play tomorrow.
Other than that, the only real notable acquisition was a rank for my Claymore, which is up to 8 now. I had forgotten it was up that high. I might need to check whether it's becoming a viable weapon for my Krogan Vanguard.
Just soloing part of a wave that far into a match is a challenge on much better maps (unless you happen to be playing a Krogan Vanguard, and even they have their limits). In an objective wave where enemies will infinitely respawn until the objective is completed, and where my ability to complete the objective is substantially reduced if my allies get killed? No, not possible.
Edit: Also, unless I'm the only one fighting that group of enemies, there's a decent chance of one of my allies gunning down any mooks I try to detonate while I'm setting it up. I learned that much way back when I was still working with the base Human classes, and it hasn't changed in all that time.
