Donating keeps server alive, people constantly worry about playercount but forget that if we had no donators we wouldnt have the server either.
You play ironman for yourself, if you want to donate its up to you.
Imo donating on ironman accounts isnt op and supports the server, whip isn't that op regards to dragon scimitar.
We still have the rsps concept with donating, Thomy needs to have option for ironmen to donate even now that loads of players spend their free time playing on ironman accounts.
Just keep playing ironman and let people who want to donate do the same, in the long run there's alot of items to get that are better than whip and cant be achieved through donations.
Gwd items (cant donate for it)
Pvp sets (cant donate for it)
Spirit shields (cant donate for it)
Firecapes (cant donate for it)
Dfs (cant donate for it)
Barrows (cant donate for it)
Donator whips might help some ironmen to start off, and thus play for longer to achieve even better items. Big picture is that they support the server and get something good in return, but in the future they still need to play to achieve better items not just donate.
tldr 1 whip donation on iron accounts isnt a problem, and supports the server
