I'd recommend at the very least just collecting the tokens. It's very likely that something will change if they decide to introduce 3-star, come 3.1. Now, maybe that might entail a lower cost in tokens for scrip gear or some form of a nerf to crafted. Maybe it will just mean that you'll have a better idea of prioritizing certain crafts at the time. Either way though, let's be honest here... practically none of us have any need for BiS or near it right now. If you have the patience, it's almost a guarantee that it'll be a win/win situation to just hold those red crafting scrips/tokens until the next craft-related update.
