I am just a casual player and I guess not your target audience, but I did enjoy the game the last couple months. I only have built up 1 decent team with a couple 6 star and a few 5 star characters. Maybe 4 of them are lvl7 or higher gear. I have limited time to play and really don't have the desire/time to build up completely new players/teams.
I hate the update, really just isn't fun this way for me.
Challenges are beyond boring now, not that they were exciting before but I didn't mind too much and was a good change.
I seldom made it to the last level of GW but usually got to at least 10. I found it to be a challenge and enjoyed it. Last 2 days I only made it to 7 and it took a lot longer to just get that far. Wasn't fun at all actually.
Bottom line for me the game was a chore to get through today and don't see myself playing any more.
I am sure those that have lot's of high level or maxed out characters will find this update more appealing but not me.
I came to the forums hoping to find out great tips for improving my experience with the new update. I haven't really found much except folks just point out that I most likely will need to build up completely new characters and max them out to have any hope of enjoying the game now.
Hope it works out for you...
