I still think they should have a repair kit. But, I will play Devil's Advocate for a few minutes.
No repair kit... balanced?
What is a repair kit? Well, it's effectively a bit of your health bar. Except instead of being part of your health bar, it's a seperate little chunk that you can apply, forget to use, throw to other people, or die instantly and be unable to apply.
Well, it isn't hard to see that removing the repair kit and adding the kit's health back onto the main bar insures that the players never have to worry about the kits loss. Effectively, you don't have to worry about the kit anymore, and the game balance remains the same.
Sortof.
The difference is in the Heavy Offense. Yeah, those guys who run into your base and start blowing shazbot and people up with equal discretion. Where is the difference, you might ask?
Well, in T1 and T2, 90% of the repair kits I earned in my experience were acquired in two ways. The first constitutes the vast majority of acquirements, and the second the remainder. Oh yeah, and the third option deals with arena.
- I was a HO. I killed people with the mortar. I used their repair kits to keep myself alive.
- I was a LD. I killed people with the mine disc or a friend and I eliminated them with two discs at once. I used their repair kits to assure I didn't need to go to the inventory.
- I was playing Arena. Someone got killed quick, and their repair kit saved my damned life.
Now, since the T:V HO doesn't have to face the mine disc, one can easily imagine that you increase defensive strength by assuring the HO can't scavenge repair kits. This would possibly be a positive or negative balance. I frankly can't tell, because I haven't played T:V.
The LD can just have a sniper with a repair pack to heal him up. Chasers never used repair kits anyways, so I don't see this as a big problem.
As for Arena. I lament the loss in Arena. Repair kits and repair patches are a large part of the Arena dynamic, as are ammo and weapon spawns. The loss of ammo spawns and repair patches and repair kits would be dissapointing, and would likely only be covered by adding in recovery (equivalent to ammo) stations on the map. Stations useful to both teams.
