Out of all my attempts at soloing weekly strikes/nightfalls, the biggest pain in the ass enemies are definitely wizards. They are such HUGE cunts, everything about them on higher difficulties seems to be fine tuned to be annoying as possible.
Wizard Fighting Process:
1.) Kill their stupidly quick to regenerate shield.
2.) Too bad their hanging in the back of the room, hiding behind shit, forcing you to use a sniper.
3.) Swear to God as soon as you ADS of said sniper is when they start peppering you with their laser accurate blasts.
4.) There is always 2-4 of them at a time so just as you start to chip away at one Wizard's health, boom, the other 3 fly straight into your face and turn you into jelly.
5.) Worst of all these assholes don't flinch. Even most bosses flinch with the right upgrades/weapons. Nothing affects these fuckers which means you never get a breather.
I've yet to complete the Thorn bounty because every time I do the Summoning Pits, I get to the last wave with the 4 shielded wizards and there is nothing I can do. It's my fault for trying to solo this only a level above the strike but it's absurd how aggressive they are.
I popped my Ward of Dawn and the way they where hammering my shield legit reminded me of that scene from the Avengers with the Hulk being blasted into the roof of that building by the Chituari. So yeah, fuck Wizards. Probably the only thing I hate nearly as much are the Cabal bosses and high level enemies like the Colossus or Phalanx majors.
