We were earning 43/45 stars in LS Hoth and 46/48 in DS Hoth... we are now earning 20-22 stars in Geonosis. That's pretty close to the expected change between the two (actually a little better, but we've all gotten better gear in the meantime). There's very little else we can achieve in the Hoth TB.
The only difference is the massive drop off in points between the expected achievements between the two. This was discussed when they first talked about the progression in https://forums.galaxy-of-heroes.starwars.ea.com/discussion/206500/dark-side-geonosis-territory-battle-difficulty-progression#latest . You can already see that even if we got 33 stars (an impossibility right now for even the best guilds), there would still be a drop in GET Mk 1. I am arguing now, that after a few months of looking at it, I believe this is unacceptable due to the incapability of exchange between the two currencies. An increase in one affects the other not at all.
