You ARE not talking about some average uo player here.Just like the guy with the 3 keeps above your post.To achieve this,one needs to invest some serious dedicated time of gameplay or feed some scripters with real life money.
Balancing a game is about the average or above average player.A full Tamer can be built with 3x115 skill points or so.Another 355-375 left for other skills.Like magery,eval,med perhaps. Just needs time and no items or gold.And dont get me started about advanced char token and jewelry,takes 4 weeks now or less? So you get a godly pet tanking for you and you can dish out some damage and heal your pet. No money or much skill behind keyboard needed for this. Not much thinking about suit and combat tatics.And there should really be no disadvantages to this? Not the slightest?
If someone decides to collect animals of different colors,fine.Nothing against that,but he must live with the fact then that he plays a underpowered template perhaps,like many other players that do things just for fun and choose a strange template. You can solo everything in this game and craft every weapon you like,good for you.The question i ask you,why are you playing this game then,you can do everything now thats possible.
