Class / arcendancy:Some are pretty decent.
Like a slayer, can have everlasting leech, and have 20%culling strike, may even have a other 20%more modifier
Oculist/juggernaut, have a build in 30%more defence, witch can be boosted to about 70%better heals when combine them with other ingame mechanics.
Overall, decent, but not as game breaking as some gear or keystones.
And verry limited, like a occulist, thats mostly 2usefull Wicked ward gamebreaking keystones, and the others are kinda shit
Or a hierophant, great MoM/es, but needs totems after that?
A Marauder, its hard not to attack but use spells.
A necromancer is pretty dam decent compared to the lacks of the other classes,
Skeletons:melee or mages?
1) mages can not be linked to spell echo, when linked to cwdt
2) melee can be linked to multistrike, if linked to cwdt
3) mages gmp shoot offscreen monsters, witch prevent mages from walking to nxt pack, since no agro, therefore mages not benefit that great from minion speed
3b) accuracy not benefits mages
4) melee skeletons can and will walk a full map, and always stay in agro range of monsterpacks, therefore nn to be recasted that often
5) melee skeletons may block zombies or other melee minions from attacking, when mages combine the damage with melee, if the agro is there
6) melee skeletons seem to be smarter then mages, never flee and agromachanics
7) overall, skellies and srs are 666%smarter then zombies/spectres/phantasm/golems/animate weapons
8) skellies not block srs, only animate weapon block srs (fly units)
So mages best for non necro classes, since the lack of accuracy for melee skeletons.
Mages pretty decent on manual casted skeletons, since spell echo can be used

lots of options, can skipp things like phantasm to free up sockets or whatever you please to, if you plan to manual cast srs alot (or totem-srs)
just the helm and the heartbound already allow a sick soo, when only cast 1 skill
if add soulwrest, and body armour, you not even need to cast
