The problem is that in x5 servers for 1 month I can make enough gold to make maximum training
And how will that magically happen ?? Speed glads don't get more gold / experience than others... That's exactly what i showed in this post.
So no, we don't get full stats in 1 month on a speed serv. Nobody does. And if you think about it, you'd understand why. There's no magic gold income, even if we can make a lot of UW3, it still gives the same amount of xp than on speed 1, and its nothing a speed 1 can't do (given 5 x the time).
There is no reason for that happening, and you haven't shown any. Yes, a lot of glads on speed servs are well-made and then train fast after 100... But that should be the case of any glad. If that's not your case, it's because you are making too many mistakes. By following proper methods, farming and spending your gold carefully (one guy here suggests only training on -40% for example), you end up max stats. And its not a question of speed.
