But are they fun to play? Debatable. Healing is slow, https://classic.wowhead.com/spell=19750/flash-of-light comes at level 20, they are nowhere the same as 29s because of that single spell. Using first aid is more beneficial as FC.
seen some retris with https://classic.wowhead.com/item=5815/glacial-stone and the damage is alright, it's better than levelers, but compared to other twinks it's kind of shit, aside from frost mage damage
