Can someone tell me all the new changes to AW?

I have not played in a long, long while and I just want a quick catch up.

Turnblocking was removed slightly (takes 50% of the stack you wish to block, just to get a small chance of blocking it). A few strategies, mainly SM, now dominate over everything else, and there are many new faces. Not much more than that, that I can say here at least

Hi Tik Tok, nice to see you again.

Like Gardevoir said the main change has been the update on turnblocking. Also, your units can now pass through enemy units. In terms of strategies I wouldn't say SM is used any more than it was before you left. IF is still a popular choice and Imperialist is slightly more popular. There is also a new strat called "Desert Storm" that focuses on helicopters but it is quite underused at the moment. Clan Wars are done a little differently now that there are seasons and clans compete to make it to the top every season. Finally there are a lot more clans and a lot more players (mostly newbies). Hope that helps!

And the only Israeli that can speak English can't play anymore, no more fun discussions.
