Further balance suggestions

[griffin1987]

Since so many of my last suggestions made it into the map and releasing the new map seems to take another halfyear some suggestions for 8.80:

- increase range and decrease cooldown of Skytank Ulti,
- nerf Heavy Tank: Mortars and Ulti needs to be weaker,
- all tanks between 7500 and 15000 are too weak except Hunter (maybe create more consumable items and cheap receipes),
- increase range of Troop Module Aura to 2000.

+ rework traider.
At the moment it's:
1. Unplayable as a newbie or not-so-good player. It's really hard to play it right, because the skills need skill to handle (esp. first skill requires constant hotkey + click spamming to work effectively)
2. Way too strong in the hand of someone who can actually play - and this holds true for start and especially later on. I've seen raiders killing titans rather easily in late game, doing port skill + heal skill + thorns, then heal kicks in and you get healed up to 7k hp while getting less damage and also doing damage to others thanks to thorns, and then you do additional damage and also get away using the port skill.
3. 1st skill becomes very useless later in the game (way too strong at start, way too weak later on)
4. please change the clickable area - it's even harder to click than heli, and from the model it's supposed to be larger than demolisher.

Suggestions:
1. Rework clickable area / model to make it more easily clickable
2. first skill should use more mana, and do more damage at higher levels (level 4 and 5, below is okay i think)
3. limit heal like ulti (e.g. 400 hp per level)


Also it seems to me that deflective armor + mass converter could stack. I'm not sure, because deflective armor says it only won't stack with burst, but mass converter says "item ... do not stack" - imho it shouldn't stack, as you could get permanent invulnerability that way to certain weapons (add in the res skill of a gobo or earth, and you're good to go with about 90% res at most and constant tank repair from mass conv, and you still have 4 free slots)

+ Make titan stun work on sky fort. Haven't seen sky fort stunned a single time by titan stun, no matter how you hit. Or, if stun doesn't work on air units, the tooltip should state so (though, I think skyfort is a bit too strong if it can't be stunned that way, considering it's 4 ups and 4k less than titan, so 10k in total)
