Some good stuff (like the repeat button on explore, gnome is fun.
But, I think you should let Guild wars every week plus one random event, it’s better to give more than less to play, and something where there are some difficulties (personnaly, only guild wars give me some) for late game player.
For raid boss, and probably invasion (we will see next week), can’t you sell on the shop the first two lvl for gold and the third one for glory ? After, yeah gems if you want for people who wants more (and pay more). And so, it will become easier to do portal7, maybe 8 for guild who don’t want to spend too much ? And for early player… Like you did for sentinels.
Guild wars makes you want to play everyday because the carrot is big enough to interrest all the guild and there are some challenges.
Raid boss just makes you want to play on sunday because you have nothing more interresting to do (and to not waste free stuff), because the carrot is really really tiny compared to the cost, lower the cost or make the carrot bigger.
So having guild wars every week plus one more event (with lower cost, or bigger rewards) looks like a really good compromise to me. Everyone happy, everyone can spend lots of gems everywhere, or having some rewards without spending any gems.
