Once and for all. The 2 factions hate each other, so obviously, gaining reputation with one would make you more detested by the other.
If you reach Exalted with Scryers you will be hated by Aldor, and vica versa.
If you decide to switch factions, it will depend on what your previous reputation was at. If you are friendly with Scyers, you will be unfriendly with Aldor. If you are exalted with Scyers you will be hated by Aldor. That means if you decide to switch factions, it will require more work to increase faction since you will be working from at LEAST Unfriendly status rather than friendly.
Word of advice, don't switch factions until you are level 70 and have nothing else to do in the game but grind rep.
