Hi,
Spell Description: The skill is capped at level 55, but the descriptions doesnt indicate that at all (unlike other skill descriptions that contain that info at the bottom of the tooltip) (link).
That seems to be a loca mistake.
Rising Tide already has a base Range of 217 (who came up with this odd number?) (link), making this a total increase of 8 range units..
since Rising Tide is supposed to be used as a Flame-Alternative (at least it seems to be), giving it the same range as Flame seems like a logical and good improvement.
Rising Tide is not a flame alternative but an additional fireball, since rising tide also becomes an instant spell. Fireball has a range of 225 and so does rising tide, which is fine.
