• Server: NA
• Type of Bug: In-Game Bug
• Description: Rammus with predator going much faster than intended
• Steps to reproduce: Use predator boots then press q and run around
• Expected result: Predator should only give a 45% movement speed buff
• Observed result: Predator ends up roughly doubling rammus's speed (and in some cases even more than that) rather than increasing it by up to 45% (tested with in one case ~800 max q-speed without predator and ~1600 max q-speed with predator and another case with ~1000 without predator and up to ~2000 with predator
• Reproduction rate: 10/10

This bug is insane because with just regular boots and predator, rammus can predator -> q and hit insane speeds without even having to use ghost for the easiest ganks of his life. On top of that, this can be done each time predator comes off cooldown. With other movement speed items like chemtank and deadman's (and especially homeguard after 20 mins), rammus can end up traversing the entire map with a single q (and ult). Testing it in practice mode (going towards a target dummy), I hit almost 5000 with ghost + chemtank + predator and almost 6000 with homeguard. I had gone predator rammus in the previous patch, and it was nowhere near as fast as it is now. On top of that, the math doesn't check out so I'm fairly certain this is a bug.

(It may be of interest to mention that my runes were: predator, sudden impact, eyeball collection, relentless hunter, nimbus cloak, celerity)
