Personally I love the thrills of battle talk - and Lae'zel's top tier Gith flirting. ^^
What does "having both act 1 romance slots filled" mean exactly?
From my perception, you can have two romances active in Act 1. If those slots are filled, nobody will approach you anymore - or in case of Lae'zel she'll tell you that too many people have nibbled at you already and she doesn't like leftovers. In Act 2 you have to decide, which one you'd like to continue with. So if you, say, started romancing Gale and Shart in Act 1, Wyll won't approach you in Act 2.
