Why?
Well, throughout normal mode, I faced many bosses. And quite honestly, all of them were pretty easy/simple to beat. UNTIL I entered Expert mode. You see, in expert mode, it makes all the other bosses MUCH more harder. And Plantera was the most largest case of this. You see, before, I could just make a somewhat large arena and fight Plantera. But in expert mode, this is NOT the case. Instead, you would have to make a much larger arena. And, you would have to make a strategy that manages to make sure you don't take enough damage from Plantera long enough for you to live. But that's not the hardest part. The hardest part, is to keep your sanity as the stupid moss Hornets use the large area To Spawn And Attack Me While I Try To Improve Upon MY ARENA AND EVERY TIME THEY APPEAR I WANT TO MURDEREVERYTHINHGIHATETHESTUPIDMOSSHORNETSSOMUCHWHYDOTHEYEXIST!?!?!?!??!?!
