Mods used to have /smite but it was taken away because of complaints. plus you could make a really Bad Gold grinder by smiting pigs into pigmen.
~ @andrewrobins
A certain mod abused /smite a ton, but that was ages ago. I've been mod for over a year and I've never had /smite.
As for the OP, I'm most likely going to be repeating what others said, but it can't hurt.
As far as I can tell, the main complaint for elite+s is not enough benefits, here are a few of my suggestions:
~ @dragon8877
I don't know which Elites you are talking about, but most people agree that Elite is the best rank for it's money, and that Supreme and Ultimates need more perks.
Unlimited Building materials: We're not talking about diamond blocks here, more stone brick, stone, cobblestone, materials that can be easily obtained from /warp wild (Only mined materials) Decrease how much you can sale those items /warp shop and you should be fine
~ @dragon8877
I'm not sure I completely understand what this is, but my best guess is that it's somehow allowing players to spawn in certain items, in which case, no, that is never happening.
New /potion benefits: Nothing to make these too OP, more like speed I, waterbreathing, ect
~ @dragon8877
/waterbreathing has already been suggested, but otherwise, I don't like the idea of adding more of those, and especially not to a lower rank like Elite. At the very lowest Supreme, but even then, I just don't like the idea.
Note that I am Ultimate and would get any of these perks anyways, so I'm not just being biased.
/pwarps allowed limited via donators :Citizens are only allowed to own 2 /pwarps, VIP 4, Premium 5, ect
~ @dragon8877
If you have the money you should be allowed as many /pwarps as you want, it's a good way to get rid of money in the economy.
Donator shops having more types of blocks: placable water, lava, fire, with spawners to sell to boot
~ @dragon8877
You can put specific suggestions for donor shop items that may be taken under consideration, but price suggestions and donor rank suggestions are your best bet to have them actually listened to.
Meebles given when you donate: If you buy VIP you get 50K, premium 100K. I not good at determining prices but it can work
~ @dragon8877
This used to be a thing, and I'm not sure why it was removed beyond the fact that it pumped money into the economy, and I guess devalued the meeble donations.
Specialized Super Mob Grinders: You can donate to gain access to super mob grinders (They pump out a TON of mobs) the higher you donate, the better the mob gridner VIP Gets spider, Premium gets zombie, Exclusive get skeleton and blaze, ect
~ @dragon8877
One question; why? First of all, this is essentially even more OP than allowing every single rank to own and use spawners, which is absolutely not happening.
/Weather [Name]: Changes the weather, nothing much to it
~ @dragon8877
If this existed, would it be like /ptime, or actually changing the weather in a world? If it's the latter, absolutely not. The first may not even be possible, but I don't see why.
/lightning strike: Sends down a lightning strike to a target (recharges every 5-10 minutes so it won't be too OP, possibly restricted to elite+)
~ @dragon8877
This command exists, it's called /smite, and I completely disagree with allowing it to players. It's not even given to Moderators, and there is literally no reason to have it.
Unless you mean purely cosmetic, in which case I again question why?
