Runes of Magic US / AU

If you look at the wiki, it appears to be a Ch/M skill. The description is as follows:

Quoted

Consumes half of caster's HP, attempts to deal a high amount of damage to all enemies in a range of 200 and reduce their resistance by 10.0 and defense by 10.0%. If the damage has been dealt successfully, the caster will not be able to move for 12.0 seconds.

(Can only be used in a Shield Form state.)

It has a 5m CD and costs 50% hp...I'd say that would warrant how hard it hits, tbh. The base description doesn't specify how much damage it actually does though, so unless the in-game one does (if it's upgrade-able), there's not really any way to tell if the damage calculation is off or whatnot.

The HP cost pretty much makes it a suicide attack in siege, except...the range is rather large though, lol, unless that's a typo. An AoE with 200 range that oneshots everyone is...a bit excessive. Should be a much smaller range.

What kind of weird op elite skills or whatever were given to champions?
Couple nights ago, we were killed by a champ, with a lousy equipment (no mean to offend, but he has a lousy equipment xD). The guy came to us and exploded causing us aoe damage for 500k, 700k, 1m, 1.2m.
Take a look, please.. i need someone to explain me what is happening here.

All lvl 60 champion elites are aoe's, some good, some not as good. Hardly think a 5m cooldown and 12 seconds of complete vulnerability for a 1-shot skill is OP especially when we still have the P/S's 1-shotting people with a zero second cooldown.

Btw, I hear those w/wl's have a few tricks up their sleeves in pvp the folks with their heads in "my gear is better than yours la-la-land" havent seen yet either
