These idiots really need to learn to schedule and announce their updates. Disconnecting everyone when people are boosting and/or fighting champions is a real game turn-off.
Won an arena fight (sixth fight, treasure chest), but got black magic before the reward. Started another arena fight, but got black magic right after the Vigor was spent. What the hell?!?
I can understand making some farmed components take a lot of farming (such as Bear Pears), to encourage people to blow a few rubies filling in their shoppings lists and such, but non-ruby gear from limited sources needs to be slightly less rare. case in point: I'm unable to complete either level 30 Leafy set because Spiral Peak and Messy Mess Area won't drop one part and Gerbeels won't drop another. This is getting silly... stuff is so rare that we can't enjoy a lot of it before we're too high level.
The Ancient Arena is the best place to level in the earlier game. I'm not in the later game so I can't speak for it, but at 24 it is the single best place to earn fast xp that I can find. It's all about reading your opponent's gear to choose one you can handle, then just responding to what they can do. As a crit monk with haste, healbomb and mass heal, I just run around wizards till they run out of power then haste, run in, and spam Hbomb and MH. Warriors, I engage, but try to time earth wave and move before it, then engage and spam Hbomb and MH. Watch out for monks, hybrids with healbomb and anyone with Express Karma! Use jelly juice, not healing/power potions, as the latter are much more rare and JJ restores power too!
The mastery skills need to be passive. At an 8 sec cooldown, you could probably use them every other skill, so halve their value and make them passive. Or make them 1/3rd their current value. There's too many active skills, no quick-switch hotkey set function and a limited number of hotkeys as it is, we shouldn't have to "activate" our masteries.
It's also worth noting, oddly, that costs for purchasing Research are not related to the progress you've made in research. Maxing tech research will cost 45 Kreds whether you're at 0/12 in Focused Beams and Technological Terror or 11/12 in them. Mad Science will cost 240 Kreds regardless of how much you already have researched.
Trophies need to add multipliers for blops earned instead of just adding a few blops. +5/10/15/20% for bronze to diamond trophies, +5% for hybrid trophy, +15% for single-powerset trophy. It'd be a quick way to both make trophies matter and reduce complaints about grinding... which at the moment trophies don't matter and grinding in this game is extreme.
