Pfft with that attitude its boring you gotta be open to new things at all times! 10k years is just time to get started! The gnomish gadgets alone open up waaaaaay more opportunities.
Eh I disagree, seeing as Thalyssras entire story was Literally a retelling of Tyrande's I think the advice while being a bit stern comes from a place of knowledge and experience around it. And as much as I loved them it spoke more towards Thalyssra and Liadrin being rancid as they proceeded to go down the exact route of the Legion. But I am very grumpy of that event in all aspects as it ruined 3 characters i greatly enjoyed in 1 horrible interaction. >.< Historically Tyrandes bite has been very good it is just shown in books. In game she always comes off as very uh... well I guess she's still there. But it's a severe weakness in the writing.
