Not sure we need more players.
We're already over the "Blizzlike" population from what I read.
What was the Blizzlike population back in 2004/2005 on high population server? I remember playing on a low to mid pop pvp server and we were struggling getting a good group for any 5 men instances at lvl 60 or for UBRS. Always lacking of healers...
And some zones such as Swamp of Sorrows were almost empty all the time (was playing horde). Ungoro Crater had maybe 5 to 12 players max on one side. Undercity/TB was always almost empy until they added AH in all cities. Even then, there was barely more than 10 players online on both cities. The major one was always Orgrimmar. No idea for alliance side.
Just throwing out some memories of that time.
On Nost, all zones were having more than 50 players all the time loll.... minus Darnassus lol (was playing alliance there). But at the very end, it backfired right in our face. The distance view was reduced to such a point it was not enjoyable to play. I could barely see another player until I was almost right at him. No sure how is distance view on Kronos (hopefully Blizzlike) , but on Nost it was disgusting at the end. 11k online was just too much and devs never should had allowed it at first place.
In the first 4 months when Nost released, 3,8k was a high peak of online players in the late evening on North America and it was great. at 7k it was becoming a problem. at 11k for peak hours at EU it was a very big issue. So no, we really don't need such a population.
''queue in line! everyone will have their turn at killing the boar. Just be patient''
Also, you can always use the Kronos donation shop to get a higher lvl character so you don't start from lvl 1.
