The 40/40 elite increases the damage done by combo shot significantly.
The 35/35 elite increases all the physical damage you (and your party) deal to your target by 10%.
I fail to see how these are not elite dps skills
The elite skills for focus regeneration make spamming wind arrows no issue. We use them more than other scouts, but hardly rely on them as anything other than filler.
As for the PA boost and viability in new zone, ill let you know when they release the numbers for the mob's defenses in the new zone. Otherwise, everything discussed on it would be pure speculation.
