My list of suggestions after playing again after a few months:
1)I don't know whats with you and singleplayer. This game is 10 years old, some people enjoy playing it alone...why don't you let them? disable cheats and that's it, I never could understand your point about this...
2)Class items are annoying. They are mostly useful before lvl 10 and they drop waay to rarely. they are useless and seeing them drop for a different class over and over is annoying. Either a)make them Epics with cool stats so its worth it b) at least triple drop rates or c) make them sell able
3) Make a carrier. Would be nice to have a horse that can't die, put some items on him and send him to "base" (where the tree is). He can get units there and use shops. Later when u get a lot of stuff that you can't drop it's annoying to go back and forth all the time.
4)remove the magic find glyph. For most players on harder difficulty it's simply "too good"
5)when I write -stats the writing is all over the place, i can't see it properly
6)Give more information about other players. When we are planing an item or something it's annoying to always ask how much do u have,etc. Would be nice to have 3 obelisks or something where you see gold, crystals,glyphs, even chosen skills etc
7)Put this on the main page: It's a program that allows multiple saves if each player has it:
http://www.d3scene.com/forum/warcraft-3-hacks/87886-unlimitedsave.html Solves the main problem I have with this game: the saving.
8)I like how glyph have evolved. Would be nice to have "team glyphs". Basically make them powerful and only allow a single one to be activated, like a party buff.
9)Enable hero portraits. As a healer it would be much easier to see, specifically when big monsters are around
10) I hate monsters falling from the sky. As a healer I dead twice when an inferal came in, stunned me and i was dead,absolutely nothing I could do, I don't think it was intended that way. Easy fix make him spawn in a different place and run towards us.
11)
First time I got critical error when saving, we where about lvl 10 or so and many hours into the game(maybe 7-8?) on the hardest difficulty and got a critical error while saving the game. In the end I ended up with the old version of the save file while my mates got the new one. We remade the game and wanted to save each hour, at .50 minutes we got disconnect. If a save system is impossible or ridiculously hard to implement I say spread the word about that program.
But we had fun. Nobody died because the game was unfair, every death except the infernal could have been avoided. The secrets where annoying but well...they are secrets. I played this game since 0.70 maybe or something like that, before you had difficulty setting for sure(much sooner) and still I couldn't find a single legendary item besides the normal once... It's annoying but I guess i'm to stupid or something.
The most annoying thing and is the saves, but I hope that with the patch things will get better. Saving every 10 minutes and playing relaxed is a much better experience. Not being able to enjoy the game because maybe you get disconnected is annoying...
