I have been maiming thief for 4 months now, playing it exclusively since I crafted bolt and incinerator for it. I am very sad to say that while I had a tonne of fun for the first month or so, I find thief just not fun.
Here are my 2 cents.
1) dead eye. This is not fun to me. I don't like stealthing forever and trying to one shot gimmick some noob looking at map. That's all this elite spec does.
2) I HATE how broken dagger storm is.... but concede that it is our only saving grace currently. Nerf after nerf after buff jk nerf. I hit like a wet noodle. In full marauder gear with berserker trinkets my larceneous strike criteria for 6-7k~ with around 20+ stacks of might.
My reaper shroud auto hits for way harder not to mention faster with trait. Soul beast auto can critical for 10k+ from range. We have nothing else that is on part with other classes. Dagger storm is so unfun to press for 4 and a half seconds of dodge and good damage with no counter play and it's not fun to be dagger stormed on.
3) I hate not having a role. We in zergs with every other medium class, and roaming is just getting 1v4 or 1v zerged. I'll have around 1 GOOD fightsevery 5-10 minutes or so. Maybe not bad to some but it's just a pitiful amount of action when compared to other games.
Fixes? I don't know. We have had so many nerfs over such a long period of time that we have gone the opposite direction of power creep.... power.... decay? With marauder gear I have 15k-16k hp.... what!?!
I don't know how to fix it but I'll be playing ranger for now.... pew pew long bow 2....
I don't want to jump on the thief I'd trash bandwagon but I feel like I've been deluding myself that the class is fun. It requires 100% concentration to play and one mistake you are deadededed.
As a thief main... seriously. Nerf dagger storm. It's not fun. And buff thief somehow to compensate.
