My list of broken, buggy and useless things regarding Lich and other races.
They make it difficult for everything to pass, sometimes units need to turn around them, sometimes they get blocked and stop for the rest of the figbt, and all other massive units make a devastating detour that takes about 10 seconds at least. Fix it so that corpses aren't an obstacle, also Tank corpses and Siege behave the same way.
Spiders turn speed and clumsy behavior around other massive units.
Incredibly slow turning speed, leads to big loss in dps especially when they target a far single among the unit, also when next to other spiders or massive units they do it all the time. Their AI when around other massive units is very primitive, keep bumping into them when out of range of their target instead of taking a smart route to get around and reach within range of their target and start attacking.
Purge The Lands.
What is the purpose of this ability? If you don't want people to play Lich just lock it... Have you even considered that there could be 100 players with Tiadrin who can decide to ruin a few dozen Lichs gameplay WITHOUT ANY CONSEQUENCE? At least make it so that it deals damage to the users castle or something or add a big mana cost to it.. this abiliy must be removed asap on the next patch, I am currently enroute in a week to Skarn because some assholes decided I belong there.
With this recent guard towers patch, I am unable to save my Acolytes to any formation, even recent or previous. Cost me more than once on big plunders...
