Ive been very active in 29 bracket on Nost (dwarf hunter Insanitty) during last month. Situation is following.
1. Im having about 90% winrate as alliance. So if you want challenge, roll horde twink and bring it on.
2. When I started twinking a month ago, gear was very cheap. I bought most of BiS blues for hunter (+some caster bis pieces) for about 5g each and less then 1g for greens. But lately I see prices raised quite abit. There are resellers that earn profit from twinking market now and more people joining twink brackets. Still you dont really need 60 to start playing competitively. At 29 you can profit from fishing or mining and get everything you need except librams which are expensive. Only very few active twinks are finished with librams and top enchants.
3. Twinking gear appears on AH all the time. Its common to see several Shadowfangs or Watchman Pauldrons. In fact some greens are much more rare. Ive yet to see 9stam/9agi vest on AH, and its bis currently since Raptorstrike Tunic unavailable.
4. Most of the times at 29 only 1 wsg/ab is going on. In prime time sometimes you get 2. Queues are either instant or you have to wait up to 15min if match is filled.
5. There are like 4 alliance 29-twink guilds. Saw some at horde side too.
6. There are plenty of 19 and 49 twinks on Nost as well.
7. Vanilla twink fights is nothing like in current WoW. Fights are longer, consumables and engineering is a must to be competitive. I dont start WSG until I have shit tons of greater healing pots, trolls blood elixirs, solid sharpening stones, iron granades, turtle food (+8 stam), rums (+10 stam). Also collecting twink gear is more fun since no hairlooms and you value every copper.
Overal Id say this server is very good for twinking, particularly at 29. You can reach this level in 2-3 days and get decent gear pretty fast. Bracket need just few more regulars to start premade battles. And horde needs more experienced players since most horde regulars dont impress.
Nostalrius a private sever? Never heard of it. A quick google showed its a vanilla server. Hows the lvl 60 pvp and gameplay? Is endgame in Vanilla as unbalanced as I remember? Where it takes months and months to make any progress at all and takes like 4 or 5 hours for simple dungeon runs?
It is the most popular private server by far with population like the most hot servers during vanilla. Hit record number of 9000 online not long ago, but its usually around 6k on average now. Im not sure what you mean by unbalanced, but MC is being done by everyone and their mom easily. BWL/AQ40 are not out yet - coming soon. Everything else is vanilla like. All quests and dungeons working, bugs are rare. There are lags and disconnects sometimes, but they became less frequent now. Maybe 2 per 10 hour session.
Leveling is painfully slow and there is constant ganking all around.
