For more realistic fights, you still want to maximize Eclipse. There are a number of "optional" talents (Genesis is not optional. Don't take it). Fight mechanics will determine which of these are best:

Improved Moonfire, Brambles, Nature's Reach, Owlkin Frenzy, Improved Fairie Fire (optional for trash only), Typhoon, Gale Winds, Nature's Focus (points might come from Furor or IMotW). In rare cases you might give up some IIS for for one of the others I listed. I'd add Moonglow to the list, but you said no mana issues.

In some situations, it would be an improvement to put Glyph of Starfall in place of one of your others.

If you ever have mana concerns, Omen of Clarity can be a huge boost for a single talent point (chain multiple Hurricanes together for the mana cost of one, get a free Starfall from melee or IS).
