For every person that loves an aspect of a game, there will be people that hates it, I personally love the RTS even though the dragon lags and dies with a handful of fireballs to the face before I can even get it to respond from spawn properly, last night pre-patch was a good example of it when I played another player with a superior army in my hand (I had something like 10 hunters before the battle even began) and had to pull out because of laggy dragon controls (as I said before may be due to the fact that I have a laptop and not a desktop which would be preferable).
Dear Inanna,
I have been able to play the DC on a laptop with the hardware which is WAY under the official minimal requirements without any serious crashed or lags. Try to set all the graphics options to low or very low and untick all effects boxes. If this does not help, also reduce your desktop resolution (this did wonders for me). The graphics may not look very pretty at low settings (but still nice enough in my opinion) but at least one one is able to play without lags
