I don't know if any of these suggestions/ideas have already been proposed, but here I go
First of all, a plugin which stacks mobs in 1 entity (when they touch each others) for example, there are 15 blazes in my mob grinder, so if they come together, it become a "x15 Blaze" every time 1 dies, the amount just decrease max amount of mobs of the same type merged together would be x100. (there are plenty of others servers that use this, I'm pretty sure I don't need to explain it more, but in any cases, it should help with server lags (not that there is much)
Secondly, it is my personal opinion, but I know I'm not the only one who feels that way. Having to have a certain amount of vote to rank up is quite annoying. I don't know if its only in my way of living, but forcing people to vote for the server feels kinda off for me. (pretty sure everyone would still vote to get rewards, but for example: I forget to vote before going to sleep, then I have a whole day of work so still can't vote, then come back and its been like 19 hours lost that I could have voted 6 more times 5 hours later). Its still just my opinion and I know why it is a thing and that not everyone would agree with me.
And lastly, there should be a last rank in /buy in the global section which would be named "Doge". Why in global section? because it would be an upgrade to one of the (VIP+/Engineer/Starlord) and it would be on all servers. I personally want to play on all servers and I like to support the server and all, I'd be willing to pay for ranks on other servers, but I don't want to pay full price for 2 other servers you see, I would upgrade for which would cost (idk its just an idea, you get to chose) something like 50 bucks, full price would be like 210$ (147.99$ with the 70% off at the moment)
Anyways, all of the above are just suggestions/ideas that "I" would like to be added, should probably do a vote to see if people like it or not, etc.
Thank you for your time.
