Not a bad idea.  There is a lot of posts already on the forums about his last stand being broken.  What do you think about giving him increased attack speed and move speed + damage reduction at low life but he can be killed.  I mean you wouldn't even have to change the name of the spell just he gets really buff at low life but only for a set time period so you can't just stay at low life forever.

Perhaps it could be changed into a weaker version of himself primarily for the purpose of commanding his minions.  His ability to deal damage would be minimal, possibly nonexistant, and he would be unable to cast spells.  He could (maybe) give a slight area buff to any nearby units and he would be basically able to control his minions from the grave.

If minions were balanced to be a threat and the primary weapon of Generals, then it wouldn't be broken.  You could still aid your team from death, but you wouldn't be invincible and you would rely on your minions instead of your Assassin abilities.

It would also help to set him apart from all the other Generals.  I mean, he would be the only one able to do damage while dead.  With other Generals, you could charge through and focus on the General to eliminate the whole threat, but with the Oak, that strategy would still leave you with a fully functional army to deal with.

Just throwing ideas out there.  I'm trying to make Generals focus more on actually being Generals than Assassins.  Thoughts?

i think it should have a cooldown maybe 1-3 min. that way he can't constantly suicide. The only thing i actually dodnt about last stand besides the fact that its not "general like" is the fact people use it to kill towers. I mean I can easily run away from an Oak with last stand but towers cant
