Alright ever since Cassiopeia's release I have been having issues with summoner spells not activating on command. however at that time I thought it was due to my keyboard dieing, (It was seven years old.), It was a logitech G15. I recently bought a new logitech G510 and the problem is persistent.
During random moments in game I am unable to use summoner spells, and some times character ability's. Normally I am only locked out of them for 4-6 seconds, but in the heat of the moment it can be crippling to not able to preform some actions for such a long period of time. Now this doesn't only happen in combat.
I could be at fountain trying to use ghost to get back out into a lane quickly, and the spell will not activate. During the time that this happens my ping and frames stay the same from the start of the game. I normally have a ping of 30-35 and 40-50 fps all game,
I am also able to move and counter with character ability's but my summoner spells wont activate. This is not a lag issue from what I can gather and most obviously because I can still play for the most part. No game play is disrupted except for the ability to use summoner spells and occasional character ability. Normally the Q skill. but this happens rarely. the summoner spell lock out happens at least two times a game. and I have no clue as to whats causing it. If you require additional information on my rig, please let me know. Thank you for taking the time to help me with this issue it is greatly appreciated.
