Hi, fellow warriors!
Just wanted to let the ones of you who are a little concerned about doing the mage tower challenge, for whatever reason, to give it a go. I did the fury one today, and it was actually one of the most exciting encounters for me in Legion, seeing as I'm not doing any hard raiding or pushing for +mythics, mostly since my gear will only barely get me into pugs and my computer sucks so bad that encounters with lots of people will basically put me at below 10 fps, even almost freeze the game. I read a couple of guides, got some buff items, and tried to do the best I could. It took me about 10 tries or something like that, but I gradually learned the encounter, and in the last try I had a good run when I didn't do any of the terrible mistakes, even though I could have done much better on adds, cooldowns and many other things. Right after, I did a few couple runs on my retripally too, without buffs to waste, just to see what the encounter is about, and I lasted a good while and had fun. I haven't completed it, but I feel more motivated to do these challenges now. So, if you're waiting for gear, or have given up in advance, do it anyway! You have nothing to lose!
