Hello!
Ive been playing both a paladin and a shaman on the HC server.
What ive been thinking about is the ability Lightning Strike for enh.
It basically double dips on your mana by both consuming an orb and also costing mana to cast.
In contrast, the new lvl 4 paladin ability is free and works as a sustain, while dealing absolutely decent damage.
I suffer from horrid mana economy and leveling is a slog. Using your abilities might botch your shield and pulling two enemies at once takes my entire bar.
My suggestion is that either you make the ability unable to be cast without shield up, remove the mana cost, or maybe even make it restore an orb instead.
Of course, all this might change at higher levels, but insofar leveling as enhancement is pretty bad in my eyes.
Regards
