I believe the issue is not just about WL. The advantages and corresponding disadvantages between classes are neither equal nor even close to being balanced.
Lately, I’ve noticed something: players dominate on the Order side, farming everyone, then switch to Destro — only to be hit with the harsh reality

For a solo player, finishing the weekend SC event on the Order side usually takes no more than 1 or 2 hours.
On the Destro side, it's often impossible to complete it at all — maybe on the last day if you're lucky… (Because most of the veteran players are either gone or now play Order.)
Forming or joining a 6-man group on the Order side takes about 5 to 10 minutes.
On the Destro side, only a handful of guilds run premades, and they usually play internally. If they need a tank or a healer, they might bring someone in from outside.
Trying to form a PUG premade often takes 30–40 minutes, sometimes even up to an hour. And usually, the group disbands after just two SC losses.
Anyway, to keep it short…
Why do people choose to play on the Order side?
WH + tree combinations are incredibly synergistic. All abilities connect logically like a well-designed chain.
WPs have been walking around with triple armor for ages. This class alone has driven many enemy players to quit. I think any balance changes came far too late.
WL — no need to say much. They’ve got everything: engage, disengage, pull, high auto attack, CC, burst... you name it.
Slayer is one of the most effective damage dealers when played with the AOE tree.
Why waste time playing Choppa with a ST build? Choppa gets 3 or 4 useful abilities from the trees anyway.
Meanwhile, Slayer has all the tools — cooldown increasers, parry breakers, etc. — and pulls it off with a 3-target / AOE build.
So, in the end, I’m joining the others — I’ve decided to quit the game.
Will I come back someday? I don’t know.
Thanks to everyone. Take care of yourselves.
Ride well, warriors.
