Just a couple of things.
The map seems nice, I've played the older versions a couple of times and so on.
But there are things that irritate me, mainly the overuse of attachments. As cool as they may be, they interfere with the actual model unless it is a fitting weapon or so. For example...
Well, I don't know if icons are legal to use or not, but DotA got Blizzard's permission for a lot of things, including icons.
Models, however are not legal unless you ask Blizzard for it.
Try using some ability that changes the actual hero (Metamorphosis for example) and have the 'run speed' set to a small amount, like 100 and 'walk speed' set to 0 or 522 (don't remember which would work better).
The one made by tinki3 though, is the straight hook, rather than the Pudge Wars one that curves when you move and bounces against objects as well as follows you wherever you go.
I'd rather go with Berserk and trigger the transparency rather than using Wind Walk, since Wind Walk is fading over the duration, instead of instantly applying your desired transparency.
Oh, right, yeah, changing that. It is MPI however, unless I'm totally wrong today. And using an increasing Integer (up to 200 or so) it could be MUI, yes. I just decided not to, since I'm guessing he's making a hero, and even if every player can have the same hero, it wouldn't be any problem.
Unfortunately, the healing part is not that easy, because it is either before or after. Being before would make it still deal damage equal to the amount if you have less missing health than damage taken. Being after, it would be able to kill you, because you take the damage before being healed...
I believe making a percentage bonus could prove more trouble than you think, but I'd give it a shot in GUI. First of all, how much health do your druid have in bear form (will his health go over 3300 at any point or even over 33000)? Depending on his health, make item health bonuses, obviously...
It is, and if you'd trigger it using a Damage Detection system and Healing the Target equal to the damage, taking damage at full health would still inflict damage and not heal because the heal occurs before the damage is taken.
What is that for? I just completely went over every step and you don't get it? That makes me slightly sad and confused myself, I thought it was a pretty good explanation.
Okey, elaborating on Glenphir's idea (the same as I would use actually).
Make two abilities. One ability that your unit or hero has, that is based on Berserk, because it will not interrupt other actions. Set the duration to 0.27 (which is the lowest, 0.01 is the same duration) and cooldown...
If you're using custom buildings it might screw things up, I'm not used to melee maps though, so I might be wrong, but check if your buildings inside the build menu are correct and not too many (11>).
Welcome to thehelper, but unfortunately, using GUI (the standard graphical interface used for triggering in Warcraft 3) is simplified from the actual code, the JASS language, which I do believe most experienced map makers use nowadays (myself actually excluded), if you wish to learn coding, JASS...
Or create 4 different dummies, each with its own version of fan of knives or something, with the casting time set to 0, 0.25, 0.5 and 0.75 for example, you could deal the damage using that instead of triggering it (causing area damage will deal damage to friendly units as well as far as I recall).
For pausing it, use bash with 0.00 duration (it WILL be permanent), the longest time, as far as I can recall (without shift-clicking) is 3600 seconds, equal to one hour.
