Someone really needs to look at Kayle properly - Its not that hard.
Kayle's W needs to be reverted back to 10 seconds (or lower) : change the healing amount to match it. This will allow kayle to use Trinity Force more effectively as well as giving her the mobility she used to have. This will also allow her to keep Rageblade stacks up better, as well as charge up a Manamune. There is no reason for Kayle to have such long cooldowns when Hybrid items benefit greatly from having spammable abilities.
Kayle's abilities need to proc her passive. Kay'le short range (and poor mobility) means you often cant chase an enemy that far. It currently takes an absurd amount of time to max her passive.
While some of these ideas may be good suggestions for Kayle's direction in the future, and though I definitely enjoy talking about Kayle and ways to make her more fun and enjoyable for the community, this thread probably isn't the perfect venue for doing so. Part of that is my bad for contributing to conversation that doesn't really contribute to the OP's original inquiry - top lane Kayle advice.
Of course I'd always be happy to talk Kayle mechanics elsewhere, but for this thread, we should probably stick to advice for the person seeking it
