I went to 78 with my center. I think as Octowned stated, with the drop to WW topping the 5:1 cap off the hop is the way to go. Great blocker is still a decent VA and if you bring blocking to 74 after strength, through natuaral level gains I think it will be high enough even with all EQ in strength. I haven't decided yet as to whether I willl be going to 74 or 77 with blocking, I have a few levels to decide though.
http://goallineblitz.com/game/player.pl?player_id=1394511By level 16 I will hit 2nd cap blocking and by 19 I think I should be at 3rd. Hitting these caps before level 21 will make your C into a monster, I had to use bonus tokens to get there, but it will be worth it in the long run.
Will hit level 14 tomorrow and be at 80 natural strength.
