Play now, considering I know there's ppl who aren't even interested in quitting blue yet let alone green, the games are still great fun vs. not playing by a landslide. Most players will endure an opportune fresh server, but not everyone, also people will revisit developed characters on prior servers while advancing new low levels on a new server, alot of players are casuals and don't want to try-hard their entire p99 career. I'll still be playing my green characters when a new server drops aside from making one main and one alt slowly on a new server most likely.
Casters are simply easier to learn the game with and gain cash, more situationally viable in most scenarios and zones if not all, and have tricks and utilities to gain an advantage that melee classes must cleave through without the benefits of. Nothing against melee classing, we need them to prevail after all. My main toon is actually the most arguably grueling and difficult to learn the game with and main with, especially on an Iksar at that (Due to more limited plate armor options vs. other races) but the risk vs. reward and difficulty learning and mastering sections of content is very fulfilling and satisfying.
