Hahaha, so you're basically stuck between Hive and Wife ;-)
Regarding the Chaos Legion phenomenon, I couldn't take part cause I've been too slow in involving myself in Splinterlands - I've begun 4 days ago, and am doing well but without being able to earn DEC yet, hehe.
If I had been in your position, I'm quite sure I would have acted the same way: stacking Hive, and then powering up.
Everyday I find more motives to build on Hive, as one of the few really descentralized and DAOd social platforms, that should be able to withstand the States' attacks within a couple of years.
It's difficult to predict how Hive will weather the attack of the state institutions but I believe it's in a better situation than many other platforms. Nice to see that you have been caught by the Splinterlands fever :-). Some time ago, I created a free online course about the game. Maybe it can help :-)
