Elemental Weapons Bonuses Return

I'm still trying to understand how E-weapon would work after this patch (Hime confused the hell out of everyone):

So for instance if an F/P mage does 100K damage currently with paralyze against a neutral monster with an E-wand 6, with this new change, they'll be doing 110k instead? Just throwing hypothetical numbers out there, but is that how it works?

Question 2: Do the new bonuses now effect DoT (From a post one basil it said that ele comp damage would not be effected by bonuses, but what about, say, it's DoT)?

Question 3: So if a Bishop does 100K with Angel Ray on a neutral monster, due to this new restriction, they'd be doing 75K instead?

Question 4: What about Elemental Decrease? If I do 150K damage on a poison-weak monster with ele wand 6. Then say I use Elemental Decrease. That damage would now be 110K (because of the bonus), not 100k right?

-Just things which need to be clarified. Thanks for answering to whoever does

1) yes
2) no
3) yes
4) Ele reset is applied after damage is calced. EWand bonuses apply then the ele decrease makes the whole thing neutral after.
