My biggest issue is that wildstar seems to send my vga to high temperatures and so far it's the only game that pushes it above 70 ?C. While it's true that room temp has raised a few degrees, it's really the only game pushing this hard on my rig, despite not being (apparently) the most demanding one.
Levelling is quite slow to be honest, but that's mostly because I waste a fuckton of time doing everything conceivable, from challenges, to actually look for lore (NavMate addon is great for this) and level my path as well.
Given my limited playing time it's not an awesome pace, but it's okay.
I did a dungeon (Stormtalon) and it was exhausting, stupidly fun, but still exhausting: tank took some nasty spikes, not even sure if she did anything wrong, certainly she took quite a beating at times, not unhealable, but certainly exciting so to say, but she certainly didn't have good threat generation, with the stalker and the dps esper biting the dust too often (switching to heal is an exercise in frustration most of the times, unit frames don't help at all). And there I thought "but it's low level so it will be easy...".
I didn't expect trash having so many hp, nor stuns that fucking kill you and you can't get out of (seriously, it says "hold" the left button and it does nothing at all, while forward and backward break the stun earlier as intended), nor raid level of challenge in a level 20 dungeon. I loved it, it was quite a while that 1 group content was hard in any way shape or form, that was pre-nerf Rift dungeons.
The last boss was the easiest but quite fun, the second was quite annoying and the first not particularly bad. What took the prize was a miniboss above a platform that took us several tries, because interrupting is too hard sometimes, yeah...
What I despise is the party unit frames: they are garbage, pure shit. I also love to randomly losing targets or getting random new ones, especially when I really wanted to land that "mind over body".
In the end it was a pleasant experience, healing as esper is quite fun and the challenge is welcome and refreshing.
Questing as esper with the mobile builder makes the class a solo god: I can kill 3+ mobs although I have to pay attention and it takes me a little bit, it's also quite fun.
I'm enjoying the game a lot so far. I'll certainly play a tank sooner or later, it seems more rewarding in terms of group leading and setting the pace and I'll very likely play a stalker, which was my favourite class in beta.
