We all have the right to complain as much as we want about the game, and we do. But some complaints have a more sound basis than others and I don’t think yours is very well founded.
Different heroes require different materials to ascend. That’s fundamental to the game and is clear in the first week you play. It’s also clear that the materials to ascend 2* heroes are less common and harder to collect than those to ascend 1* heroes, and the materials to ascend Bane - the first 3* we are all gifted - are considerably less common and harder to collect again.
It hardly requires a massive leap of inductive reasoning to conclude that more powerful 4* heroes will require even less common materials that are even harder to collect, and 5* heroes - the most powerful in the game - will probably need something really rare and difficult to find. This is not rocket science.
So while this may technically be true:
it is pretty obvious from the first week of gameplay that the more powerful a hero is, the rarer and more difficult to find ascension materials will be. I don’t see any need for that to be spelled out further.
Especially because, hey, this forum already exists to provide answers for seekers of knowledge. If a player somehow managed to play for a while and be surprised at how difficult it was to find ascension materials for 5* heroes, they could always follow the in-game links to this place, where all their questions would be answered. (As I believe has happened in this case, QED.)
No, it’s not.
Because not all players are happy to relax and accept what the game gives them. Some choose to accelerate their progress by spending. As always, I’m grateful to them for funding the game, but there are no guarantees in E&P. Some spenders will be lucky in pulling good heroes but will be frustrated by an inability to buy the materials to ascend them. Some will never manage to pull the heroes they want. Some will pull great heroes and luck into the ascension items they need in ascension packs - maybe even doing so cheaply.
If you have a short attention span (like, 3 months short), don’t enjoy the roller coaster ride of low probability events, or would prefer to be able to buy guaranteed success, then this game just might not be for you. It’s all about grinding over time, accepting that runs of both bad and good luck will happen. Or spending a wheelbarrow full of money.
