I am going in order for these, from left to right in the /kits list.
Changes/ removals:
Barbarian- Make this a sharpness I iron sword, and give 5 steak, and maybe a stone pickaxe. As of right now this kit it very under-powered. Yes, it’s the first kit, and shouldn’t be very good, but it should not be to the point of that everyone who uses it has a disadvantage.
Miner- Looks good to me, maybe add an unbreaking of efficiency enchant? Just throwing out ideas, :)
Cook- This kit used to be very good, and very useful, now, no one uses it. I’d say go back to 5 steak, and 2 golden apples. It was actually useful that way. c:
BeastMaster- Not a bad kit, but no one uses it, and there is not really a reason to. Either make all the wolves 1 bone to train, and add more wolves, or remove it. Imo, remove.
Snowman- Right now, it blinds opponents when you hit them with it. No one uses this, it could be useful in some situations, but it’s useless in most. Remove.
Tarzan- Completely useless. Remove.
Poseidon- Used to be useful, made it bad. Make it regeneration 1 in water, and constant water breathing. Nothing more, nothing less.
Builder- Not all that bad, but not worth adjusting. Remove.
Archer- Never seen anyone use it, I think it gives 32 arrows, and a punch 1 bow. Not worth it, bows and arrows are easy to get. Remove.
Healer- No, just no… It should have regeneration 2 forever, and maybe 1 or 2 healing 2 potions.
Lumberjack- More food, maybe a diamond axe?
Smelter- This should just give you the iron/gold as soon as you mine it. The point of this kit would be to get iron and gold as quickly as possible. Making a furnace and punching it with iron ore in your hand is faster, but not worth it. Either fix what I said, or remove.
Sonic- The speed 2 was perfectly fine, it was slightly op, but speed 1 is too underpowered.
Cookiemonster- Remove the strength, healing, and resistance effects and add some negative effects, and you’re good.
Leech- Sorry, this kit is not bad, but too hard to fix and not be way too OP. Remove.
Stomper- This one will be controversial, but it’s too OP. Make the kit give you diamond boots with feather falling 4. It’s too OP as it is right now, and if skybases are going to be added back (as they should) this kit will be too OP.
Tank- If I remember right, this kit is full leather...Seriously? Remove.
Wither- Give wither 2, and make the effect longer. Not worth the kit as is.
Ghast- Really? This kit is the most pointless kit ever. I would say remove it, but I think there are ways to make this kit better. I had an idea for the kit to be able to hover for 1-2 seconds. Would be useful when taking skybases, when falling, or even just going across a small gap. It could be a very good kit, and very much worth it, but not too OP.
Alchemist- I don’t remember what this kit gives/does, but I do remember it’s very bad. Remove.
Magician- Not a bad kit, add more lapis, and a stone pickaxe and I’d say it’s good to go. :)
Fireman- Good for team killing I guess? Who wants that.. Remove.
Guardian- Has diamond helmet and iron chestplate right now. Not really a way to fix this one and make it worth using, without being too OP. Remove.
Maniac- If I remember right, this kit gives 2-3 seconds of strength from each kill. That’s not bad, but not really worth it with the smaller number of players playing walls these days. ;( Remove.
I will need help with names. ;p
New kit ideas:
Multiplier- Maybe something that gives double or triple the blocks when mining stone or logs? It could be very useful for getting blocks to take down a skybase, a much more efficient.
Stomper kit is PERFECT please don't remove or under power it! Everything else was right :P Poseidon..Psh...
And the Tank desc was perfect just..perfect..
Stomper is finer for now, but what if they make the height limit go back up, so there's actually a possible chance for a skybase? Then stomper will be too OP. The 0 falling damage against a skybase is too OP, skybases pretty much rely on fall damage. :/ I love stomper just as much as everyone else, but it's too OP against a skybase
Healer with infinite regen 2 would be the new Poseidon except without having to be in water. I think it's fine how it is.
I also disagree with the sonic being changed back to speed 2. I still use it with speed 1 and with speed 2 it was kind of OP on a lot of maps.
Tank is ok TBH, it gives full iron helmet and pants, prot 2 leather chestplate and feather falling 2 chain boots
Cookiemonster should straight up be removed; no one used it before people found out exploits.
Oh and alchemist is a fine kit. It's not that great but it's viable and I see no reason to remove it.
I'm pretty much on the and page with the other ideas though.
