Renewal fix > get GMs to remove all fixed portion from spell breaker. Problem... MOSTLY solved. The rest of it would revolve around balancing bs skills like Suicide.
What worried me would be the enforcement of petty skills being casted. Dazzler, frost joke... these things are a giant waste of the GMs time. That is.. on classic. Renewal... yeah... you guys have worse stuff to content with.
As for leap, it only works if you can leap northward. That affects very very few castles in the final room. To counter it... afk something on the landing tile. You didn't see it coming? Well awareness is a strategy! I was portal casting backslide in the test WoEs, it's effective in about 4 castles total. The thing about that is, you should know your castle and know your enemy.
If any portal casting fix doesn't prevent the third party abuse it's pointless.
Oh and not that I support a lot of portal casted BS, but I do like portal hide/portal cloak, because that stuff should go through portals. It shouldn't require a change to the players state to progress from one room to another. That's the only defence I have of portal casts.
