Donāt go for a build with too many classes, well rounded doesnāt mean useful.
Link1 is useless, 5 mobs is too few for late game, good for PvP though.
Cryo 3 has 2 good skills, subzero and frost tree, also ice wall if you have kino. If you are cryo, 3rd circle is a must, subzero chances have a huge gap and frost tree is awesome for all purposes. But well, there goes 4 ranks spent on low rank classes.
Same for pyro, few useful skills, but makes a nice combo with linker instead of kino, which is much more useful for lategame, since bosses are the only place where icewall+pp shows itās power. When you consider no mob can tank this ā ā ā ā but itās not as easy to use and not as many times as it sounds like, you might go for Pyro since it stacks actual multihit damage.
Wiz3 > Pyro or Cryo, that simple, for late game content, considering monsters SPR for cryo and low damage on pyro, only Fire enchantment and Frost Tree will be good, wiz has a very useful set if you know how to use it.
Rune Caster without wiz3 wonāt be really playable, you can melt bosses in seconds, but thatās it, in high-level arena there will be too much Oracles and PDs for you to freeze anyone.
Link 1 = 5 links. Link 2 = 8 links, there are no such thing as 5 mobs population for late game, Link 2 makes you kill enemies 60% faster than Link 1.
Necro and Sorc are not so bad, they can probably turn out to be useful for future content, I believe shadowmancer goes after sorcerer or necro.
Warlock and Featherfoot are awesome, in rank 3 they will probably be massive damage dealers.
