So your point is that creep side is overwhelming freeps with their superior dps?
I find that creeps have an edge when it comes to getting one specific target down instantly in rapid fights, whereas the freep side by a long-shot has the tools to overpower opponents by pure constant damage output, while having a distinct wider pool of debuffs/buffs/stuns/mez/knockdown/cj/area damage at their disposal.
Also in your example of a RK EC'ing for 7k and Hunter US for 10k, sorry I don't believe they are hitting that low in the first place, secondly add all the damage boosts a freep group can have on the target and the hits become 12k and 15k. While the creep damage stops after Impale (DS)/VT, the freeps can follow their big hitters by nearly as potent skills.
To back that arguement, RK can follow EC by ceaseless arguement+Shocking words+lightining bolt (or the new AoE lightning toggle skill), which stand only a little bit behind the initial EC damage.
Hunter I really don't know so much about to make a fact based opinion here, but let's not forget that each time the target hits 50%(70% from traits) morale, hunter can apply -50% inc heal. (same CD as dev strike)
And they still are the top ST damage class.
I'm a big believer in pure-dps classes which I consider being champion/rk/hunter/burglar and from my recent experience, the freep groups tend to fill up with secondary damage players which I find to be the biggest obstacle as far as being competitive against a group with same/bigger numbers.
Along with the previous thoughts, bearing in mind the last update, I find it useless to go into ettenmoors without maxed mitigation virtues, which is something new to many that I've met.
So to counter your statement that in numbers creep side are superior to freeps, I challenge you to make a group of 12 consisting of 2 healers,2 captains(red+yellow), lm, rest pure dps classes and go fight 12 creeps with same defiler warleader ratio that your captain/mini ratio. If you still find freeps to be weak, ill rescind all ive written and apologize.
