If Warlocks are fine in arenas, and fine in bgs.. does that not conclude they are...fine? I'm not sure what else is measurable for your conclusion they are not fine?
Just because you can walk with crutches doesn't mean you leg is ok.
Face it, after they nerfed some of the tankiness from warlocks it made us very clunky with little defense and escapes.
There is a ton of prep needed for locks to be on par with most classes.
We have to set up a port that's some what easy to be pulled out of range of and countered by shadow step which has zero setup.
CoW - other classes do it better.
CoT - yup, other classes do it better.
CoE - see a pattern here?
Shadow Flame - (glyphed) yeah... Tell me you would take that over Dragon Breath.... Didn't think so.
Tons of hard casting for demo and destro for sub-par burst.
Don't get me wrong a handful of tweaks and it's a great class without being OP. We were left limping after a bunch of nerfs and changes with little thought of survivablity in 1 on 1 or tight situations.
No, your analogy makes no sense in this context. If someone can win the olympic 100m with prostethic legs are they still crippled? Warlocks are the most over-represented class in every pvp area.
Port, because we can set it up, allows us much more active strategy on our escapes than other classes. If your porting into a grip or step every time that's on you.
How has tankiness been nerfed? soul-link is still operating, we have massive self-healing
COW, as far as I know is a unique debuff. 10% less melee damage that also causes increased resource cost (with jinx) that can easily be spread due to 2 minute uptime and range.
CoT is similar to DK Necrotic strike, without the healing absorbtion. However, different classes are different. DK cannot easily put the casting debuff on multiple healers/casters while still doing damage. They are no ranged.
Dragonbreath compared to shadowflame is grasping at straws. Mages and Warlocks function differently. Fire mages have to continously hardcast spells to deal damage, we have to put up UA and Haunt (12 seconds of not needing to hardcast for damage, then able to soul-swap to a second target without casting.) Fire mages need some way to get spells off.
