We’ve had an issue for a while where skillshot line missiles have been occasionally unreliable at very close range. We’re testing a fix that addresses those close-range issues, and that we believe will also improve the reliability of skillshots at all ranges.
In order to fix this issue and several other bugs pertaining to skillshot line missiles, we've re-engineered the way skillshot hit detection works in our game. As part of this change, skillshots now fully take into account the model size of the target champion. This makes skillshot behavior in our game much more consistent (and actually results in a very small effective difference between champions with different sizes, so it won’t impact the way you use skillshots).
In order to retain the current gameplay we have on the Live servers, we've had to slightly reduce the range of most skillshots since targets are effectively slightly bigger and thus slightly easier to hit. Although this is a numbers nerf on paper, our intention here is to keep the overall gameplay feel of skillshots the same as previous patches. The game should feel the same, with the benefit of more reliable skillshots.
Keep in mind, sometimes skillshots may appear to miss due to weird lag conditions, but this fix is aimed at addressing the most common issue players were experiencing.
Hopefully you guys get a chance to test these changes out and please leave us feedback on how they feel.
*** UPDATE: We will NOT be releasing these changes for this patch unfortunately due to several severe bugs found and reported by PBE. We're looking to polish it up further and ship it in a patch in the near future. Thanks a lot for all the reports and concerns guys, we'll continue this conversation soon(TM).
