I like this Season so far.
I've almost completed my fire-based Shield Bash Crusader (still need to find a Maximus, haven't found a single one since S4 began), and already I can very comfortably do T8 and T9 (although I do have the raw damage for T9, the survivability becomes the issue in some situations, but I can still do T9 nonetheless).
I've also recently been gearing up my Witch Doctor and can now do T7 to T8 easily enough (just need to watch out since I'm rather squishy but I'll change that with defense Gems eventually) with the Zunimassa set (five piece, but a cubed RoRG to get the sixth piece bonus). Not to mention that I'm also using the Grin Reaper helm... now that one made one heck of a difference (which I totally didn't expect). The fact that the Mimics use skills that we use is awesome and they spawn very often since the proc rate seems to be very high even if you'd be stuck with low attack speed. And, on a side note, the Witch Doctor class itself is entirely new to me, the WD I made this Season is the first one I actually geared up to do "end-game" with ever since the game was released back in 2012. The class must have changed a lot since then, because what I do recall of the WD class back when I first tried it (in late 2012 I believe) was only being bored to tears and never touching it again, until now. I'm having a lot of fun with the class now, brings back good memories of my Necromancer in D2.
Now... I think I'm going to start gearing up my Wizard (which is also a class I'm not that familiar with). Not sure which actual "build" to go for. I'll just start by trying to get full Tal-Rasha's and from that point I'll see what I can come up with.
