A thought on solving some of Kindred's gameplay pattern problems
Remove the limit of being only able to have one champion marked at a time, to allow Kindred players greater freedom. As is, the current mark system is flawed in that you're required to telegraph your goals in order to snowball even slightly. Removing the limit that only one champion can be marked at a time, while retaining the cooldown on marking champions, will greatly reduce frustration and make Kindred much more fun to play, and easier to balance since the marks will be more reliable while not making Kindred overbearing.
