Obviosuly, I assumed most people would realize that by going Paragon Multiclass, I had taken the three power swap feats throughout the levels between 1 and 11. I guess I should have been more clear about that...
Anyway, your reply to my post had nothing to do with my post at all. I know how paragon multiclassing works. I also know that Warlocks get a set at-will depending on which pact they choose. They also get Eldritch Blast as an at-will.
Pact Initiate warlocks get the at-will of their pact choice as an encounter power. At level 11, with paragon multiclassing, the only other choice the spreadsheet is giving me for the at-will is Eldritch Blast. Now, normally, this is fine, but if I am a Half-Elf who took Eldrtich Blast for his Dilettante power and then got the Dark pact at-will as an encounter power from Pact Initiate, then when he gets to level 11, he should be able to pick from the other Warlock at-wills for his replacement at-will power. At the same time, this should also apply to non-Half-elf Pact Initiates, since Human Warlocks can pick from the other at-wills when picking their third at-will power.
