There is a growing trend in weapon releases I've noticed recently. A lot of the newer weapons, like Shy, Barrier, Tolchock, Patient Boy, and of course the infamous Rock and Roll, are all so incredibly useful, many of them even giving the character an additional special ability, that all the other weapons are quite obsolete.
I don't point this out because I want awesome weapons not to come out anymore (except in the case of Rock and Roll), but because I'm questioning the game philosophy for the second and even third tier weapons. I realize the beginner weapons should be fairly simple and straight forward having the least amount of utility and complexity. But why make second and third tier weapons if the 4th tier weapons and on are going to be so radically different and useful as to render the 2nd and 3rd obsolete? If it was a progression thing where you had to be higher levels and pay more money for each progressive tier I could understand. But it's not, somehow the game, through cost and drop rate, wants me to believe O.Shtorm is equal to Tolchock, or that Popcorns is equal to Cookie (hell Bubblegum isn't even good as all three of it's common counterparts and it's a rare and costs more), Granny as good as Barrier.
When I get these 4th tier weapons I don't have any reason to build the 2nd or 3rd tiers I have. I just got Shy, why the hell would I ever build Raceme? I gor Rock and Roll, why would I ever build ANY other of her weapons?
I guess what I'm saying is that these 2nd and 3rd tier should cost less and some shouldn't even be considered rare, as they are quite useless, like Bubblegum for example. 1st tier should be cheap, 2nd should be normal cost, 3rd should be a little bit more and 4th tier should cost the most. Then there would be incentive to build lower tiers. And rare weapon costs often do't reflect the effectiveness of the weapons and so there are some rares that collect dust because there's nothing great about them to merit the rare cost. Prices and categories should change.
