Changes I've made to X:
Wooden Blade Matrix
80/100/120/140 damage per second. 130/150/170/190 manacost. 30 second cooldown, as opposed to 20 from before. Speed bonus has been removed, but no collision remains. Later in this post I will explain why.
Deus Ex Machina
Lasts 3/4/5/6 seconds. 30 second cooldown, as opposed to 60 from before. No manacost. Everything else is the same.
Hero Stats
Strength - 25 + 3.2, changed to 25 + 3.0
Agility - 10 + 1.5, changed to 10 + 1.65
Intelligence - 14 + 1.4, changed to 14 + 1.0
Base move speed - I've found to my amazement that it was set to the default TC's ms, 250. Holy fuck. Changed this to 305.
Try playing X without Wooden Blade Matrix, you'll realize how slow he is, even with boots. The original purpose of the skill was to catch up to opponents. Look at any game with X in it: currently, when most people use Wooden Blade Matrix, the intent is to kill them with the damage from the spell itself (because it's possible, and very viable to), and once you stop spinning, you get at most one or two hits off on them with your melee attack. It is also a very devastating AoE.
Sometimes it's necessary for spells/heroes to deviate from their original purpose on paper. WBM in its current state doubles as both a chasing skill and an escape skill. The changes you've suggested may make sense at a glance, but the problem is that you can't attack while in WBM. If the damage output is too low, you'd basically be disabling yourself. It might be worth it if X had some sort of disable or slow, but he doesn't. With these changes, WBM becomes less of a chasing skill and more of a damaging/defensive skill. Also, 5 seconds isn't long at all; it only seemed long because of the distance you could cover in those 5 seconds.
Changes to Y:
Ultimate Pies
It appears it wasn't working because the aura was 0 AoE. At least, that's the only reason I
think it wouldn't be working.
Underwater Flying Car
All-around buff. It now has a 50% cleave, its SPECIAL BEAM CANNON now scales in damage per level (100/225/350), and it has a spell called Burst, which maximizes its move speed for 12 seconds. Also slight buff on damage and health. Oh yeah and kaboom was removed.
Changes to Z:
Muscular Augmentation
I changed it to a berserk-based move speed increase with trigger-based hp regen. So now it WORKS PROPERLY COUGH TIP COUGH.
Piercing Spines
This is now an arrow orb. It costs 50/60/70/80 mana, has a 10/6.5/3/0 second cooldown, and deals 7/8/9/10% of the enemy's current hp in bonus damage.
Grooved Spines
I want to scrap this for something else. Reason being is that why does Z need a range upgrade when he already has move speed bonus? The whole kiting thing is just stupid theorycraft that doesn't work. Sure, it lets you attack towers without them hitting you back, but that in itself doesn't justify a skill slot, since towers take forever to kill and the creep wave will be coming to sexually assault you soon anyway. However, I don't know what to replace this with yet, so it stays for now.
