I had to change both gear and spells to stand a chance of competing at anything close to where I was before.
My first character, Assassin had hit L50 and completed the story shortly before 0.36. The final chapter was a big challenge, and I was able to complete a Difficulty I dungeon through spells to stun lock opponents. I couldn’t do Difficulty II as one regular hit would kill me first turn. Gear was mostly Rare and L15-25. Nothing Epic or higher - I hadn’t found any and evolves weren’t possible in 0.35.
The 0.36 update gave me a few bits of Epic L35 gear which almost doubled my gear score (~700 to ~1300). The double-hit of spells increasing in cost, while mana generation from matches also going down meant I had to change my spell loadout. Now using Channel Darkness, Nightmare Vision, Unnerving Strike and Night Blade. There was a Northelm crystal available the other day for beating the daily L55 Dungeon I. I tried 10 times and the furthest I got was killing the first enemy. So much health and armour vs doing so little damage.
Since I only had one character at 50 before the update, and with progress on 0.36 pretty much halted I have instead switched focus to running alt characters through the story. Here the L35 gear makes it a cake walk. Paladin and Necro each breezed through to Ch12 / L40 with barely a single loss between them. Having high level gear effectively level up with them every level makes it so much easier, but not something new players would have.
Daily PVP takes much longer, and as a result really doesn’t encourage wearing your best gear. You are now much better off equipping lower level gear to match against a weaker opponent that you can (with a bit of luck) kill in fewer turns and therefore score more points. High level slug fests are both boring and penalised.
I like the addition of the daily skirmish and dungeons, though the third Difficulty I-X could perhaps be more targeted at something possible for the player. If I’ve never beaten a Difficulty II skirmish or dungeon, offering me a Dungeon VIII and saying it is “Hard” is a bit of an understatement.
