Are you going to remove dodge completely?
Eventually, yes
If so, what have you decided so far about champions with in-built dodge mechanics?
We will adjust those to new mechanics or wrap them up into similarly-powered stats. Jax utilizes it for gameplay decisions, while on Udyr it's more about the damage reduction and power of it than a gameplay decision. Case-by-case approach.
What was the logic behind removing dodge and nimbleness from the mastery tree?
Since this has been the plan, removing dodge (and therefore Nimbleness) is a piece of 1). Nimbleness was a cool mastery - if dodge was staying, we'd have left it.

and a question MANY would love to hear: If you plan remove dodge completely, WILL Riot refund those IP to those with dodge seals and quints?
We will be doing something to make this right for players. Details to come, but our plan is specifically about making you guys happy in this regard.
