I didn't actually mean to suggest that the BTD game should also have 4/4 towers. I just thought it would be fun to imagine such. And even if they did exist in the BTD world, the challenge is still there to reach those levels. They are expensive after all.

One more thing, I was 95% finished with my projects (third path, ultimate (4/4) forms, Temple of the Monkey God Mk II) when the Monkey Sub came out. Still trying to figure out the set of upgrades for the new tower. Actually, before anything else comes out shooting my ideas, please make sure you understand that they are just ideas. I got a lot of positive comments when I first posted about my projects.

As for 3/3, 4/3 or 3/4 towers, my project doesn't include those because I started my project thinking of limits in the first place. I set up the 4/4 upgrade such that:

Tier 3 upgrades of Specialty Buildings enables towers to access 4|4 versions of themselves for 10 seconds (permanent for Banana Farm and Monkey Village). All x|4 abilities are accessible upon towers' transformation.

So basically, the ultimate form is just another ability.
