It would be lovly to have a option to switch between specs.. F.eks could have a 1 spec support and 1 spec dps. There could be like 15 – 30 min re-charge time upon swap of specs.
Just my 2 cents..

Not really needed as there is a holy trinity and the respec fee is a flat fee and very low. The idea behind this is you have to be prepared for your runs and if not you have to adjust to your runs with what you have.
