Return of Reckoning

Afaik this topic was addressed in some form before, but not sure if there has been an answer for it.

Engineer Warlord Set has +2 on grenadier but has:

3. Bonus Weaponskill
7. Bonus Armor pierce proc
and also as stats 19% AA Speed (4+5+10)

these 3 seems a little bit weird after all, are there any changes planed?

All 3 royal sets for engi have poor choices in stat distribution and set bonuses. You can work stuff out through mix and match though. I would not use warlord strictly for grenadier
