Haha, don't lie to yourself I'm sure the campaign is far from balanced.
I can make that lizard thing easier if it's too hard.
- Eats a unit dealing 1500/2000/2500/3000 damage per second. Has 10 second cooldown.
To what?
Maybe increase cd to 30 seconds or add the chance to avoid his devour if you will step back in a correct moment when the lizard comes close (but its much more complicated) so I think that 30 seconds cd is a key.
For those how think that in some sets heroes are overpowered - you got op phodom or others after give up usage - but before you have to do a lot to earn sufficient amount of money (atleast Ch.6 I suppose), or you got them easy-walkthrough using invis-aura and afk... omg isn't it boring? If you think that in such battles (with normal creeps and mini-bosses) you'll easily benefit from such strategy - then why not to try
**** when you don't have a chance to revive using lifes? Why do heroes in some complicated buildorders and ultimate sets have to be counted as overpowered? Don't forget that this campaign is not only for those how spend 10000 hours on it already but for the first-timers also.
In other words I mean if you know how to build really powerfull heroes - just use
**** mode, the question about moving after the target with invisibility and burning it - it is even more boring than using cheats...
When I mentioned about using of all 3 characters - I meant special epic and elite events when such invisible tactics in most cases sucks hard.
If you'd nerf such things - you will found out that the campaign became completable only for the "some kind of experienced" players - no attraction for new-comers as it'd be too complicated.
P/S I'm pretty sure that I made a lot of mistakes in this post - sorry it is late night for me already
