I sure hope my bard still reaches 100 perform without the combs then.
I wouldnt worry about it. It's a good change (I'm a culprit also....). But what I can tell you from before I got a lot of these:
1. skill from character = 43+10epic = 53 . minimum charisma bonus = +2 (+6crafting) so ~55
artist feat = +2
2. from items+spells
comb = 8,
crating items x 7+ =14+
spells: Sirines Grace +8
and just find another ~13 from various (bard)equipment/crafting and/or charisma bonus. It's not hard to get.
Edit (a few more skill point possibilities):
-Heroism +2 or GR heroism +4
-Bard items slots (rings, necklace,boots?,armor) with ~5 perform which give you +3 more than crafting for the slot, if you needed it.
-Eagle's Splendor is ER boosted = up to +6 (from +12 stat increase)
