Here's an idea: move object to area (not task object) for a fantasy campaign if you want to have some sort of warp point.
A unit editor to edit the overall stats of a particular unit so you don't have use individual actions to edit the name/hp/attack ect. You should also be able to decrease hp and attack without using the work-around, (c'mon this is 'merica, we don't need t' do all that subtracting from that really big number)
Namable Locations! It would be nice to lay out and name all the locations before making triggers, it's more managable and easier (no accidently selecting a unit when trying to lay out the area.)
movable locations effect, can help add some randomness to the scenario.
variables (less-than, greater-than, equal-to) No more tedious work-arounds using a dummy player for special triggers.
more multiplayer support to a the trigger system, for instance, a way for the object selected condition to detect WHICH player is selecting the object so if selecting the object spawns objects for the player selecting the object, than more than one person can activate the trigger. Like OBJECT-SELECTED BY CURRENT-PLAYER ("Current Player" being whomever selected the object, not a set player, if that's understandable)
Well, that's all I can think of. All these ideas were borrowed from the Starcraft campaign editor (Why does a 2-year older game have a 100-times more powerful campaign editor than the later one???)
*EDIT*
Ahhh, I thought of more:
AN INGAME SCORE BOARD!!!!!
It would be really nice to be able to keep kills, razings, buildings destroyed, deaths, conversions, ect. scores for victory and rank conditions and special trigger conditions without using resources to keep score. Also you should be able to create custom score labels (eg - Player one has 126 peices of the true cross or something to that effect.)
A FREEZE GAME effect that would freeze the game while two objects hold a conversation, like maybe a Knight Hero having a monolog with the player just before his death in the midst of an epic battle with the enemies frozen all around to make it real cinematic or to keep your units from attacking other units and distracting you from an important conversation.
A CENTER VIEW AT UNIT so you can can maybe center the view at an important random event, like a hero dieing or something like that.
These are yet more features added by Starcraft that sadly weren't implemented in AoE II.
