have specialization utility skills that are only available when the specialization that its from is selected. example: selected fire specialization would add more fire utility skills to choose from in your utility skills pool, and if water is selected, water util skills are also available. (hopefully more skills from the gw1 skill library will be added to increase game-play and help solidify gw2s combat.)
traits are very system wide but lets have more individual tools to use with more skills.
maybe gw1 attribute points and skill line system could be imported to gw2 to enrich gw2 game-play range (it’s already made, why not import it and let gw2 players use it. direct port might not be possible but modifications could solve that.) and there’s lots of useful gw1 skills too.
