It makes more sense for the OSRS gold later because the battle itself is determined by the tick system and it prevents people from being able to obsessively eat to get out of bad situations.

Other things that I believe need to scrap the tick rate are skills like farming. It is really annoying how inaccurate growth cycles are just because they move on a significantly longer global tick system. If systems such as vents can be come back later with a timer can't skills and toss 'em out?

 I also think that it's ridiculous that many potions are still not on a timer like overloads are but rather drop according to a international tick. It is extremely annoying when I use a dose of a potion to reach the specific amount I desire and then 2 seconds after my stat drops since I chose a bad tick to consume it.

I guess my point being that I think ticks should still be about, and they do not will need to be quicker (the global cooldown on abilities is faster than FF14 by way of instance, though that game has lots of off-cooldown skills you may use immediately.) But clearly RuneScape has heaps of different tick rates going on at precisely the same time, so why not uniform them better or remove some of them completely in exchange for real timers?

1 thing about server capacity problems,they are Cheap Rs gold probably due to overpopulating hardware servers with virtual servers. They are currently trying to jam way to much on their servers at a time.
