As sejuani, She is kind of squishy during the early game, especially when her Passive is down. It is quite easy to lose that Passive so she needs to be careful.

Besides her Ultimate R CC, her W E CC combo is quite hard to land due to the fact that the enemy can easily kite the combo out. Therefore, Sejuani needs to be really careful about her movement.

Can’t gank very effectively until she hits level six and gets her Ultimate R. This gives early aggressive Junglers an advantage over her which they can then capitalize on to shut her down.
