Element TD is my favorite game on WC3. I just got Reforged and started playing with other people but I noticed a bug. I was doing same random, short game. I only had 2 elements, but after making a level 2 tower it gave me the option to make any x2 combination tower, even those combinations of elements which I did not have unlocked. Also, Well towers appear to require Water Level 3 for some reason. It would be really cool if 4.3b got a fix to 4.3c or 4.4.
