If you're not planning to PvE then you can skip those two; Diagnostic Scan and Kolto Cloud. Those are pretty useless in PvP. DS is used as a filler heal in PvE and to get your energy back a bit faster (if talented, DS crits give you 2 energy per tick). Kolto Cloud on the other hand, is good for operations. I wouldn't run without it It's more situational in flashpoints; good if the whole group is packed together, otherwise it's pretty much wasted energy. You can only use All In if you have your companion with you. Which is not possible in operations.

The easiest solution for this bug for now is: Run this encounter in a Nightmare mode. Really, the mobs may have more hp and hit a little bit harder but it's nothing an average geared group can't handle. We kept wiping in this over and over on hard difficulty due to the bugs and had to reset the instance after every wipe. Then we swithced to Nightmare mode and...oneshot the encounter. No bugs. (Almost) free loot.

Signed. I dunno why but yesterday when I got dc'd I could immediatly log back in without waiting in a que, when my guildie had to wait for ~hour. But today I got random crash and when trying to log back on I was placed in a quite long que This needs to be fixed asap.

I'm having this issue too. And lag only in warzones. I'm fine while questing/flaspointing/etc, my fps is 70-90 and no lag, but enter warzone and fps drops to 30ish or under that. It's playable sure but the lag is really annoying.
