Why not? I'm at Arc 80 now, I'm free to spend my money whereever. For now I think I would follow Emberguard's brilliant professional advice of indulging in the luxury of speedrunning GE. All further boosts of my attack is simply for the sake of spending even a minute shorter doing the tedious unrewarding slog called Guild Expedition. Time is gold after all, wouldn't you agree?
But when talking about this particular player, a newbie that doesn't know left from right, and you tell him to actually Battle on places other than GE, naaah, I am going to tell you why that's bad.
No one has criticized your decision to pay to play. Why the consistent urge to bash, dismiss and disdain those who are free to play? Your game play decisions may work for you (debatable), but when you repeatedly insult players and promote your methods as being unquestioned gospel, naaah, I am going to tell you that's bad.
I am usually too lazy to go look things up but in your case, since you're special, I took a look. Imagine my surprise when looking at all the US game worlds I only find your one city, and that one nowhere near Space Age -- unusual since you've had a lot to say about later game play. You got that expertise where? Other than an Arc80, the next highest GBs are a CF11 and a Cape10, the militaries are well lower. Oh yeah, an AO with a few levels on it. Otherwise unremarkable city. On your 4th guild since March. Battle count low enough to be considered far from expert.
Your first post in this thread was an insult to the OP, and the rest were all off-topic as none addressed the op's stated question which is how to maximize Traz's capabilities as he moves into the next age. Your opinions regarding fighting vs negotiating, ge vs gbg, pay vs free are all irrelevant here -- you want to listen to yourself talk? Start your own thread and stop hijacking this one.
@RufusXZ, I wouldn't worry about how many barracks to put down because your space, pop, and happy needs are going to help you decide that. I agree with Agent that maximizing Traz involves carefully picking the units you want it to produce. I also agree that the rogue and grenadier combo would be a good one to start with, although full disclosure I haven't fought in Colonial and base that suggestion on advice of those who have.
