With the dinging of 75 i immediately Went to town, updated my totems, bought new FS and Trained and macro'd my beautiful lava burst.
Lava burst at level 75 without glyph of lava crit for ~4.1k (x3 instant 12k.)
Lava burst also increased my dps on bosses by 500dps and increased my dps on trash by 300 dps.

At level 75 with standard rotation i am at
toon 1: 1320dps
toon 2: 1300dps
toon 3: 1280dps

*note they dps meter showing was from this fight only consisting of me waiting 8 secs after 8 secs after 8 secs to get a cool screen shot. (lul 600dps >.<)

Looking forward to more spell dmg etc, (buffed at 1218 spell dmg)
