Welcome back! ^outraged loves helping "new" players, send him a DM for help!
If not, then im sure ^thumpr can give you some advice he did lots of climbing last season
Actually for guardian questions he should ask
or
...
Jokes aside, if u talk about groupplay go multiheal as ability, the other 2 are useless (salvation works if u tank aswell as heal)
If you play solo, go salvation and some dmg ability that isnt guardian (powerstrike or something like that) But I wouldnt recomend guardian for solo, it's terrible for clearspeed/dmg.
