I always loose against sorceresses
Sorceress with 95%ES will be one of the hardest matchup you can be pitted again. You have to keep on desync'ing hoping that some of your hammers connect before they replenish their mana (I Know alot of 95%ES sorceress who pots on blue) and kill you.
Don't hesitate to use 95% Resistance if the sorceress decides to use 95%ES though. It's all fair.
I'm devising a possible way to beat them but I'll need to do some testing before I can be certain that it's effective.
Wind druids are a bit easier than high ES sorceress, there are several ways you can defeat them. ALWAYS wear Ravenfrost.
Defensive:
Lay a hammerfield in what I call a 'web'. Basically you'll be trying to entangle the druid in a DENSE intersecting hammer field, and you will stay there as a bait.

All summons should die and if he lives, he will teleport away to recast his summon. Now if you're quick you can use a delayed namelock with vigor and kill him while he's casting.
If you're not quick enough for that, just rinse and repeat. It will either be you or him.
Offensive: (I've only tried it once)
Convert your hammerdin into a hammer/smite hybrid by:
1. Dumping HoTo for a Grief PB (35+IAS)
2. Dumping Shako for a Rockstopper + 15%IAS jewel
3. Dumping whatever amulet for Highlord's wrath.
It will give you a total of 70%+IAS, and you should hit 6fpa smite, and 75%FCR and 86%FHR.
First you must lay a field of hammer around the wind druid. That should break oak and some minion stack. When in desync do a namelock smite. The druid will use a spirit instead of stormshield, so your smite HURT ALOT. (Note: The advantage of smite is that if you namelock properly, you always hit the player NOT the summon.)
