I made the difficult decision to start from scratch on one of the more populated servers because I couldn't find anybody to raid with and my guild cancelled all future raids on Bondar Crystal. At most there were typically about 40-50 people on the fleet in the evenings. New server had 3 times that on just the starting planet and last night there were over 200 people on the fleet and another 170 on the planet I was questing. I hope that eventually I can migrate my lvl 50 GS and Sage over to merge with my new toon.
On the note of subs/server pop comparison, I tried WoW again over Spring Break and during peak hours I found a handful of servers with Standard load (none higher) but most were Light. I found 1 person in my starting area twice from levels 1-10 and one of them was the friend who urged me to try it again looking for me.
