It surprises me this thread has remained so silent. With so many people here who complain at everything that goes wrong, it would have been nice if more people shared in the positivity of this week.
So yes, a very good week. For me personally 350 gems from the PVP event, 300 from the Birthday Event, a good chance at getting 3 lvl X runes for free at the Cell Event (and 250 elementium if I wanted to). All of this gives lots of incentives to continue playing, after a period of quite deflating changes.
Of course how this is perceived will vary from individual to individual, but from what I have seen in chats and groups it gives mid range players the idea that they can continue their struggle to catch up with the higher level players. It also softens the feelings of the less well-to-do higher level players that the introduction of Book Restrictions and 'strange' rules like 'triple flame', 'triple water', 'double spirit' and especially wars with incomplete books put them back to where they started. The end game still changed (as it should), but this week's generosity gives people (at least some people) the idea that they are still involved in playing for this endgame.
