Some problems people have with Kronos:
- cross-faction mounts
- character actions
- 10g respec cost
- no easily accessed video section / "what we provide other servers don't"
- no consistent video content to keep the hype alive (what do your players link their friends to convince them to switch?)
- wonky website that, while very clean, leaves much information to be desired
- When searching for addons, Vanilla, 1.12 etc, Kronos never comes up. Do some SEO work on your Twinhead, armory, etc
- apparently no mention of World channel (you can manage one server side), making the server seem like much more of a wasteland than it is
- apparently low PvP activity and no administrative incentive to do anything about it
- no pre-nerf content (not talking about items and quests)
Some things Kronos does right
- having mechanics/classes polished up
- having content released and more scheduled to be released (very important, capitalize on THIS)
- having a stable server and lots of support from Twinstar is stronger hardware is needed
- some transparency
- focusing on quality
- dynamic respawns (although they're a bit much imo)
Some issues people have with Nostalrius
- too high pop/lag/shitty respawn on resources
- bugged movement in PvP (SERIOUSLY, CASH IN ON THIS GUYS!)
- bunch of PvP bugs that are annoying and won't be addressed
- pre-nerf content not REALLY being pre-nerf, just vaguely so (SERIOUSLY, CASH IN ON THIS GUYS!)
- missing features and missing content
- no transparency
- lots of gold exploits at the start, putting people far ahead
- honor system hardcapped and not 100% blizzlike
What Nostalrius does right:
- SEO, you can almost NOT avoid finding them on the internet searching anything (vanilla) WoW related
- creating more hype by consistently releasing content videos (even if content comes slowly)
- attracting players who have literally never played WoW before by advertising the "true experience"
- having a well designed website that provides all the information you need (or at least the information to cash in on players)
Take from that, what you will. Personally, I only "play" Vanilla to hold me over until TBC. I didn't even intend to play, but developing Questie got me into the game again. I'm now level 44 (very casually got up there) on Nostalrius and have a lot of my spare time invested (which I don't have due to working a LOT). If I do make it to 60, I plan on PvPing, but currently I do not see that as a possibility as a melee on Nostalrius. Therefore I am on the verge of switching due to some of the issue mentioned above, but with the way x1 is, I'm quite commited already and am still holding out a bit of hope for them to run a second realm (or as they said, upgrade the hardware to handle 10k players).
That being said, I think a lot of players are in the same boat as I am. Convince us to switch, make it obvious that Kronos is the better choice and convince us that the population won't dwindle once we've invested another 7 days /played on Kronos after switching (I cannot press the importance of SEO enough here, SEM for all I care).
I think a lot of players on Nostalrius are extremely frustrated atm and you can really cash in on that, be the lifeboat to their sinking ship. However, having a high quality server only doesn't mean shit if you can't promote it properly. Take a look at the time Vanilla was almost dead and Valkyrie was the only somewhat quality server around. They didn't bother listening to the community and they didn't bother with advertisement (that includes voting sites) at all. When they really had a chance at making it, they blew it. And that's really all there is to it. Don't let Kronos become the same way. I am already convinced it is better than Nost, but to play this game, it requires more things than just being better (namely, players) and people really need to be convinced they won't waste their time (again).
tl;dr promotion is key
