lotusvenom: changed DPS increase from 4 to 20.7 (290/14 = 20.7)

Your math correction is incorrect Edit

Battle Shout(rank 7) provides 232 attack power. Five talent points invested in Improved Battle Shout provides 290 attack power. 290-232 = 58 attack power difference. 58/14 = 4.14 damage per second difference.
