What is the logic in rewarding top KD's with more trades? The top KD's are the ones who already trade (along with 75% of the utopian KD's), crosslog, etc. Top alliances like ABS and Cov basically get to clip the few weak spots they have and further their monopoly on the server.
Sure, on paper it sounds great. Give all KD's a chance to challenge the top and get more bonuses but it won't work out that way. The idea of legal trading is a good one but rewarding the KD's that are already the best at it is counterproductive and won't achieve growth in the game as you'd like it to. If you want to attract more players (and a new player with NEVER be invited to a top KD) then rewarding the top KD's won't do it.
