I think it's was great, even though I'd rather use my DS. My LS does outnumber my DS, 56 vs 30.
I'm not that powerful at all, my Toon's GP is only 436.7K, roughly 391K when TB started.
Phase 4 was pretty much my "wall".
The Combat Missions were fine, I'm sure I would have done a bit better of my Guild was able to fill in all the Platoon slots. Which, oddly, I found the most fun. The team coordination and communication was key, but also unlike regular Raids and the Daily Guild Activities, you really were dependent on Guild members.
I felt it was the most fun Bingo game I've played in a long long time.
I look forward to TB using other factions, but can't use the same TB formula until other factions have at least 15 Toons, like Galactic Republic and Empire.
