Interesting thread.
Just to give you an idea. The final 2 units of the last guild war (Dauthus, Tormentor and Dauthus Avatar) had a combined attack of 78k raw. With the boosts that we have, my attack from these two units increased by >300k.
So, yes, the gap will widen as long as players on the top continue to have interest to get those units.
Whether it is good or not for the game in general is another question, but an easy one to answer.
The "sad" part is that many players literally spent 10,000s of real $ on units that very soon will not even be used in their army anymore.
