As a jungler this is what scares me the most about Senna

So I playtested Senna on a PBE game and noticed that her ult grants vision where she shoots(Global and lane wide btw). This scares the shit out of me. I figure out that if you angle the shot correctly in the correct spot, you can gain vision of EVERY CAMP EXCEPT SCUTTLE on a certain side of the map. This is absolutely nuts, but Ulting you can automatically know where the jungler is, what he's doing, if he's near to try and make a play, also if he ISNT there you can rule out where he could be(In base, invading, or even taking a drag/Baron). This is one of the junglers main weakness if you know where they are you can assess what can happen with that info. Hell even if you don't hit every camp you can still hit one entire blue side/red side and rule out where they ARENT. Please make it so the laser only gives you vision and not the whole fucking thing. Smart players will abuse the shit out of this.
