Or overpowered.
Yes, but then it also could cause what you called “issues at (un)expected places”, not necessarily with Teleport, The Oculus or the Illusionist Passive, but with build balance (similar to how Deathwish + old Etched Sigil did it in the past), at least if the damage bonus is too powerful.
Technical repairs might even a lot more development time than implementing your and mine suggested changes combined, since you first have to find and analyse the issue.
Increasing the animation speed might be easy, depending on what the issue is with it.
But in case it is also a deeper rooted problem, I would not count on that.
Yes, this definitely would be easy.
A few month ago iirc I made an illustration about how it could look like to edit the gamefiles of D3 based on my experiences with modding D2. It of course is very, very, oversimplified.
That estimate was based on how modding worked in D2, which looks like what the guy is doing in the video I linked above in one of my earlier posts, or in these screenshots I made from modding some of the actual D2 files.
According to the devs it is even easier to do these things in D3, and you have individual files (or ‘Snows’ as they are called according to Jay Wilson) for every single skill and probably every singe item as well.
Jay said that you just have to open the file and change the numbers, so it apparently is very easy to do that.
Removing the micro cooldown should also be easy, if it also is located in the game files.
Yeah, that is all nice, but it would not help the general Wizards mobility. You still only would be mobile if you have Aetherwalker and to not overpower the damage bonus, it would not be be competitive, which means it rarely would be used at all, except maybe for niche builds or speedfarming.
My point is that even if you are looking for a easy and quick solution, that still might not be the best one. But you are definitely right that it still would be better than what we have right now.
