Are Paladins really bad?

[Foxplay]

I prefer paladin or sk for groups on my cleric simply because almost nobody ever takes dmg except for the knight. Warrior mitigates more but occasionally other ppl or myself will take a hit or two. All the small little heals to top ppl off from warrior tank not having aggro for a few seconds really adds up

Tldr; small heals to fix dps taking dmg every so often cost more Mana than you save by healing a slightly beefier warrior tank
