I'll be the devil's advocate here and defend CG.
The past week has been tumultuous, with DSTB bugs, yoda mythic backlash, hSTR, etc. But some of you folks have definitely overreacted...
firstly: NOBODY lost any rewards. We're all just assuming that the next time it shows up, there won't be any mods. Now, this definitely may be true, but all they're saying is that they will remove mods until they figure out how to display the thing properly. this DOES NOT AFFECT ALL MYTHICS, so calm down.
The "substantial makegood" has yet to show up. If it's bad, I'll be handing out pitchforks, but let's just wait and see. If they compensate us properly, there's no need to get pre-emptively upset.
DISCLAIMER: this refers to players who have a GP of about 1.5-2M or above (i.e. played through the CLS meta or before)
The arena teams you've possibly built include Titans, Nightsisters, RJT, zzEP, or the like. RJT murders P1, zzEP can get you 2%, Titans nets 3/5 for Chex Mix, and you're more or less Heroic ready.
TB has already made clear they want strong players to band together and weaker ones to stick together. hSTR is just another step in this direction.
If you're a whale, move to a proper guild. If you're someone who thinks he's not heroic ready, look through your roster, build 3-4 teams and put forth an application on any of the guild recruitment areas.
If you want to play with friends, fine, but don't expect to get Traya or G12+.
