I only really played the normal kits and some of the op ones, so I can't say anything about the classic, soup and insane kits.
Generally I think the kit selection should be available to everyone so people aren't forced to play kits they don't like. Also I would like to have the option to make a "custom queue" so I can select a set of kits from multiple categories and then will be matched with anyone who also picked one of these kits. Maybe that kould be a rank perk instead of the basic kit selection.
Also I noticed that many players don't know that there is an attack cooldown and they only deal minimal damage by clicking as fast as they can. I think there should be a plugin that displays a large warning to players that click too fast (with the option to disable that warning, but not too easily so they don't disable it without reading it first). I sometimes try to tell people about this feature, but they don't understand or don't believe me, which is not that surprising since most other servers disable the attack cooldown.
All kits that contain blocks currently bring the risk of your opponent just pillaring up or even blocking themselves in permanently outside of the map. There should be a maxmium build height (somewhere between 5 and 20 blocks) and it should be impossible to place blocks outside of the map.
Favourites:
Iron Warrior - Nothing crazy and short fights.
OP warrior - I actually like the speed effect and very long fights sometimes.
1.9 Warrior - Strategy is very important and it's great against hackers.
Survival Games - Great kit, I like having a sword and a bow, the fights are a bit short sometimes.
UHC - I am very bad with this kit, but it's still nice to have some change from most other kits.
OP EggWars - I like the kit except for the missing block height limit.
OP UHC - It's a fun kit although I think it would be better with some normal golden apples instead of the enchanted one.
Kits that would be good if you could choose not to play them:
Eggwars - Too short fights and missing block height limit.
Archer - It's not a bad kit, I just don't like getting it randomly when I want a sword fight.
Hunter - Sometimes I just want to play the game myself.
No Debuff - It's ok, but I dislike pretty much all differences to the OP Warrior.
Dislike:
Trapper - The fights are way too short and the outcome seems almost random.
OP Archer - The armor is way too strong.
Health - The fire aspect is just annoying.
Bomber - I just don't get it, but it might be ok as an insane kit.
Ninja - I don't like the blindness.
Explosive bow - Another kit that might be ok as an insane kit.
I would like to add two more kits:
- A normal kit with iron armor and an iron or stone axe
- A op kit that is basically the OP Warrior without the potions (and maybe with food)
