first of all @ blood moon: glaistig is not telling the truth, at least not the whole truth^^
with his 300 attack (and his other stats, which i know from watching his profile) he/she's really not one of the storngest mp5 players, but a long way from as weak as he tells you here xD
i myself have quite miserable stats for an mp5 ( 120 att, 200 def, all the other things 40 or less) but still manage to play good because i sozialize with people! All you have to do is finding someone who needs anything (easy wins on critters or losses are best to give away at my postion, as i'm very very very off-balance atm (400 win to 600 losses)) and then get something back from time to time, example: ghost hunter was asking for victorious battles a few weeks ago, and seeing a chance, i started to attack him with a rit that could never possible win and that gave him a vic almost everytime. Lateron, he tried to get losses, which i happily gave him. Now he remembers my name, and whenever we meet, he kindly uses his amazing vit to give me easy xp, which are very hard to acquire for me in regular battles atm, making me stronger than i could ever have grown without help!
All that stupid babbling is just to say that everyone can win when one finds helpers, and i know very few people who can grow really strong on his / her own.
to come back to the idea: i dislike the idea of bounty-hunting people who violate the dojo, it really is enough punishment if those people don't get help in the dojo, which they will need in the long run. Even if they have a friend who helps them, there will come a time when one freind alone is not enough for that player, and everybody who thinks he can manage on his /her own, here's a warning: i tried to do that, and it didn't get me anywhere except on the hate list of the folks i killed!!!
And meanwhile, you really need to set up defence rits ( yeah i know it's hard if you have no high elemental and no high tree, but it can be done) to save your critters from being killed while training, you have 16 slots and can only use 6 critters in a training rit, so it shouldn't be a real problem, seeing that not many people attack in the dojo like madmen^^
p.s.: there's n o need for a def rit to stand chances to win!! just set a fresh grasan and let him die in a 0%-vit rit, there's no need to set a def rit that wins the incoming battles, because that WON'T WORK, there's always people who can bash you with no troubles at all^^
