B is a great concept, it should be a quick way of getting a ranked match against interesting races.
Having recently started humans however I have rapidly become dissolusioned as lower ts matches are just stuffed with crazy metagaming teams designed to kill teams developing normally.
Fummbbl has always been about a if you cant beat em join em mentality and one has to stall, foul, push etc to survive. But its a step too far to me as there is just no fun in it.
Examples of these teams are:
http://fumbbl.com/FUMBBL.php?page=team&op=view&team_id=528508 - With Borak 5dp ts 140
http://fumbbl.com/FUMBBL.php?page=team&op=view&team_id=512767 - 105 Ts 2dps
http://fumbbl.com/FUMBBL.php?page=team&op=view&team_id=515045 - not so bad now but was 14 vs 10 with 2 dps when i played them with rookies
Solving the rr rebate (especially leader) may go some way to resolving this. But my humans played 10 games against teams so ridiculous there just is no fun anymore.
So back to ranked for me.
