Necromancer and minion summons?
Just as a general note, not to offer an opinion on Necromancer minions, but the game will give you enough skill points to buy every skill, and then some. Never feel as if you’re wasting skill points. By exploring different maps, gaining levels and killing champion enemies, you’ll earn more than enough skill points for everything. The only wasted skill points are ones left unspent due to indecision.
For open world PvE they’re great! They help you fight, offer some neat utilities and get the aggro off of you. For dungeons they are bad as they’re one-shotted by most things in there, leaving you with no utility skills and on your own. But dungeons are worries for later, by the time you get to those you’ll have enough skill points for alternative skills to swap to for dungeons.
There are many who love them, as seen above. For me it was not until I got rid of all minions that I started to enjoy necromancers. Try them out by all means, but remember what Xiahou Mao wrote in that you will not have issues unlocking everything.
Minions are a great way to start off. Minion-Mancers (MM Necros) even have a small niche in lower tiered PvP. And you know its good when you see it used in a competitive setting.
Their only real drawback is the very little control you have over them. If you’re not careful, they’ll aggro things that just shouldn’t be aggro’d and wipe your entire party.
When that happens and your party rages, just tell them “minions are undead and therefore brainless, can’t do nothing about it so just deals with it” (that normally gets a few chuckles and keeps the party moving)
