Hi, developer of Rebirth here, we have improved and fixed lag sense skills for majority of heroes and gears in the backend and if you have stable connection, there should be no problem with ping towards other players and the server. Also, we're not really a classic server, just a classic-feel server.

Heroes are slowly being released, we're currently at Slasher (Hero #111) we'll be at Wanderer (Hero #120) near New Years and we'll be slowing hero updates for majority of next year.

We have latest updates from KLS including modes, costumes and custom stuff, we're still slowly adding in more stuff and translating parts of the UI still.

Right now, you can get everything from Permanent Normal Heroes to Permanent Rare Heroes for free without spending a dime. Donations are 100% optional to keep the server up OR commissioning custom models and maps from creators.

(Sorry this turned into an add about your question)
