The thing is, you speak only for yourself, not for ANY others.
You said yourself you can never have enough gold unless you have all heroes 5*,lvl105,fully skilled and trained.
In theory this is true, in practice for me and a lot others gold is the least of the ressources stopping to achieve that. its more gear to r2 the 60iest+ hero, Warhall ressources and gems to train the 30iest+ hero.
But for a lot non Vips or low Vips, especially when reaching lvl104 and 105 with the high costs for enchanting and skilling and maybe Rana xp buys, gold can be a factor stopping them and certainly will be if level cap is increased (and skill and enchanting will be even more expansive)
And you don't realize that a cap, especially like it is now, is no benefit for them. What does it help them that others also get less, but still enough (from crusade eg) to easily have enough for skilling, enchanting and buying tons of bronze chests, while they don't even have enough to enchant, skill all the heroes they would like to and then still buy chests?
It's just a selfish dumb behavior your showing...
