At this point, that's all you're going to hear. The flavor of the day every day at other forums is badmouthing IMT.
You're delusional.
I usually hear it's because of the capcom characters on IMT and the reputation of it being usually used by uneducated (at least for mugen)
creators between the ages of 5 - 14 who literally just spriteswap the template rather than make their own original hypers or edits to the
actual template themselves. But I rarely ever hear why the actual template itself is bad. The only bug I heard is that it has a spammy AI.
If the moderators will let my post be seen, I'll explain some of the problems to you.
1. It's a template, but barely any of the coding has any notes. Aside from the stuff they copy/pasted from Phantom of the Server, there are barely any code blocks that leave comments for creators that are attempting to create using the template. In addition, they completely removed the information left by Elecbyte in the constants at the beginning of the .cns.
2. The .sff is horrible. Instead of using Kung Fu Man, the character has a single black standing sprite and the required gethits. The .air doesn't display any clsn standard on attacks, basic/system movement, or even the gethits (This part is the worst). Newer creators that use this template are simply left to imagine what the EOH standard (which doesn't exist btw) for clsns are since the air doesn't display any clsns outside of anim 200.
3. There are no examples of how special attacks should be implemented. All of the specials (and I'm sure the hypers) are essentially the same.
If a user had interest in adding attacks similar to Jin Kazama's rising uppercut or Evil Ryu's dive kick, they have no example other than their own imagination. Counter attacks and projectile attacks are also missing here. Because of this, you'll notice that most (if not all) EOH chars in the EOH full game that use the EOH template play far differently from each other (The template character has an infinite with LP btw).
Marvel Super Heroes, X-Men Children of the Atom, X-Men vs Street Fighter, and Marvel vs Capcom 2 all have some standards for when velocities are applied and when they're over. The template has no information of how and where velocities should be implemented.
4. The template has tons of syntax errors... that Mugen ignores for whatever reason. "Sprpriority" is misspelled in many instances, making it useless.
There is no uniformity.
TL ; DR version : The template has a huge problem with consistency, explaining how and why things work, and a lack of effort to help users understand how to make their character play in a manner similar to EOH (Although this in itself would be pretty difficult since EOH has no consistent gameplay style).
Movement feels sluggish.
The hitdefs have poor definition (No yaccel, getpower, givepower).
The sounds in the .snd are low quality (Especially the hitsounds. Holy hell...).
The FX come from several sources and clash.
The EOH template was created by an incredibly inexperienced coder.
