Toph-- i mean Talyah
Ok reto make her W knock up area bigger arround and at a slightly longer range as your dmg is dps based you should out range an annie who can and will one shot u the moment she gets 6
Make her E detonate faster (bc u can walk from one end to the other b4 this thing goes off and it takes a lot of stupidity to still be in it when u get like 6 seconds to leave it so its only good if you lane your W into your E, change it.)
Reduce her cooldown on worked ground and make the one projectile thrown on worked ground do .5 Ap Scailing as true dmg + some base dmg and her none worked ground is fine just add more of an incentive to hit more then 2 or 3 as the dmg on the last one or 2 are literally garbage
And lastly give her R a passive 10% cdr that is lost when ult is on CD or make it usable as a dmg spell (such as all foe's hit by the wall take 30% increased magic dmg for 6 seconds + a 100/200/300 base dmg with a .3 scaling and turn her wall into still a wall but with a arrow head at the tip and the ult she can control for a distance (obvs reduced bc half the map ults like that is broke af) like that dope snake game we all played as kids)
u did it with Rek and kindred i know u can do it for her as shes so not meta i have seen people doge when i select the champ or call me a retard for playing her and that she sucks bc she has no supper hard cc and shes sooooo squish
