I think as a whole totemic restoration should just have totems be a longer cooldown, i.e instead of reducing the cooldown by 50%, maybe 25% would be a good number.
Windwalk totem owns as well, 45s tremor imo would be fair.
Despite ele / enhance being kind of bad, having a tremor for your healer every 30secs is a little extreme. Your healer will get out of fear as often as a resto shaman would.
LOL? 45 s tremor would be okay? are you fucking high or something? jesus christ
