I've been thinking about this and still it doesn't jive
I'm sorry but its
2 pips for warrior (physical melee)
3 for ranger (physical ranged)
4 for caster (multiple variants, wanding and staffing)
and 4 pips for the fastest physical melee type?
who gets mana return on crits and increases crit chances?
who attacks faster than any of the above?
who can use zealous mods (casters cant)
who can use maintains better than warr and ranger (only 2, 3 pips)
which given all the above suggests they'll make mana possibly faster than any current caster character designed today to only do just that?
Also given all the skills are mana and most attacks, as pointed out R/A will also be arguably over the top. Sure you lose the assassin primary but everything sooo much cheaper with expertise and once again load up with zealous - yikes.
Just make a lot more sense at 3 pips. I think about what my warrior does with 2 in some combinations with zealous, and think about how much over the top a 4 pip melee zealous crit-energy returning spamming assassin can do, ie I'd be surprised if a/mo >>> w/mo, biggest reason being the pips & speed & zealous mod results even before factoring more crits + energy.
Guess we'll see what happens!
