Yeah, I was subbed when I played, and I generally found that it was possible to skip the really crappy ones. For example, I was Pub side for the most part, and found it was quite worthwhile getting to 20 or thereabouts on Coruscant, in order to only have to do Class missions on Taris. A combination of liking Coruscant and hating Taris with a passion made that by far the best option for me. But that's what it mainly comes down to, and why I said it'd be easier after your first toon, is personal choice. Certain planets will grab you with their atmosphere, or the nice flow of their mission structure, while others will annoy and repulse you based on the same factors. And man, I really really hate Taris. It seems like every mission-start is a 1000 miles from its component parts, the landscape is full of dead ends that look on the minimap like shortcuts, the flipping rakhghoul quest hardly ever works... etc. And by the way, if subbing is not an option, try to get preferred if at all possible. It carries a few decent upgrades from straight up f2p, and I think you only have to spend like $5 on cartel coins, which will themselves come in handy in shoring up things you're missing out on from Sub status.
