What is Jayce's Intended Weakness?
A core part of LoL champion design and balance philosophy is that every champ is supposed to have areas of strength and weakness.
Artillery champs like Xerath can outrange everyone, but are frail and slow up close. Skirmishers like Yi do tons of sustained damage, but are squishy and need to be in melee range to do their thing. Jayce is a hybrid Artillery / Skirmisher. Other Skirmishers can't kite and poke like Jayce; other artillery champs lack his self-peel, mobility, close range burst, and defensive steroid in hammer stance.
What is Jayce's intended weakness? Not a rhetorical question. What do you think his intended weakness is?
Personally, I think when Riot gets around to nerfing him, they should either reduce his self peel or mobility, to make him a proper artillery champ, or they should reduce his range and poke damage to make him a proper Skirmisher. He can't be effective at every range, while also having the mobility and CC to keep his opponents right where he wants them.
once. Although you have to catch him by surprise or he will just get away from you.
