I like the idea of portals being weaker and gates being stronger. Maybe lower portals to six total range? It's just a bit of an issue that they're 2 range longer than everything else. I don't like solo or duo units that say "you must fight on my turf or you lose".
One army that proved to be an issue in 2v2 (I can't remember who was playing it) was two conjurers and a priest.
