It would be definitely beneficial to those who buy elite , but will create a glory creep between the two groups . As of now the attacker and defender get glory based on scaling . With that in effect a non elite defender will get less glory , which kinda sucks .
Just compare it to main game elite , it gives you more rss to progress but doesnt affect costs of breeding and tower build time . Same with atlas elite , helps you build more troops for you to kill more and gives you more rss ( gold and hats) to build more troops .
Another problem I see is that it will still promote hitting below . A diamond team will still hit below a sapphire 3 in ranks and get normal + % buff to an acceptable level of glory . We saw this scenario with the double glory week where people hit left and right cause all was double.
I would strongly disagree to elite changing that way .
