1. If by balancing you mean making a blob of unskilled teleporters that any kid can pick up and duel with, then yes off-class skills do "balance pvp"
2. Godly in this case meant stuff such as his current rb flail of quick,
19-20/1x lr scs, 35+ combats, etc. He dueled without those and won. We choose not to try new things because we dont want to be part of that blob mentioned already.
3. Explanations for the temple restrictions? I think Lovely already went over them..but here they are again
a. No lifetap because it just becomes a race to see who gets lucky and casts it (sometimes it happens twice in 1 duel, sometimes none in 5 duels)
b. No doom because one of the harder skills to do w/ a paladin is aura flashing, especially now since it can be done for a second or less only.
c. No stacking auras, pretty much same reason as b., that it's a skill that includes timing, patience, and strategy.
Those are the ones that stand out the most, except they've been discussed already, these and others.
Btw, do you want a cookie?
