RAID UPDATE: I was uninstalling the clients, and just for the last time I launched lamannia and checked the loot tables. To my surprise there are changes in the upcoming patch. The "main" raid loot chance increased by 1% for most difficulties (ie. in end chest it was 3% on ee, it's now 4% and so on). Also "items subtable 1" was updated with the same tome chance as "subtable 2" (ie. 3% on ee, 2% on hard etc). So +5 tome chance looks better now... previously (on ee ofc) it was:
3%*50%*3%*10%*90% = 0.00405% (so 1 per 24691 runs)
now it's:
4%*3%*10%*90% = 0.0108% (so 1 per 9259 runs)
It's still 4+ times more rare than pre-expansion chance for shard of ring of spell storing in adq1 but, but... turbine is so generous, they just let you skip 15432 runs of new raid!

Seriously though, there will be more than 1 chest, so it doesn't look that bad.
Also even the +5 tomes looks unbound, so someone pulling it might make a fortune putting it on auction. The cosmetic pet otoh is btc.
In any case, please no more loot questions, both clients are gone now

Sorry in advance if all this will become obsolete info with yet another patch.
EDIT: One more thing... I have yet again dumped a copy of default skin from lamannia version of the game. It usually takes turbine a year to release it and I just have to press a key, so here it goes, completely untested but probably ok:
