MiniMap Clarity

Was playing a game today with an Ivern on my team and I noticed something. Later in the game when Ivern clears a buff camp an extra buff is left behind for his team. I happened to notice that the minimap symbol for this buff and the minimap symbol for Zz'Rot portal are almost identical to each other. Blue buff matches friendly portal and red buff matches enemy portal in game. Its a small issue since the portal is almost never placed in that area but it could be confusing for some. Anybody else notice this?
