it literally says early access or alpha (on Xbox), epic fixes most game breaking problems within a days time. they constantly give updates on game status on their website and on social media.
explosion damage isn't random, rps and other explosive weapons have set damage counters that make it the same no matter what. they have nerfed smgs quite a bit, lowering ammo per mag. dpb, and even removing ones that are too good, such as the regular mp5. again, they give set ranges to make sure that people don't go around trolling with a pump that hits for 100 to the body from 50m away, which is also why they made the shotgun pellet system. epic didn't necessarily not try to save other games, which is not what my comparison was trying to prove, they, unlike blockbuster and toysrus, can make money different ways, i.e other games. with a company with multiple products, when one lowers its profit, with another one of the companies games taking it's place, there isn't a need to do everything in the company's power to save that game, especially when the game is not only rivaled by one of the developer's other games, but also when there are other games like that that have much more revenue being brought in, i.e league of legends/smite (in reference to paragon). they are a business, which is trying to make money,not necessarily because it is greedy, but because there are people that work there that are passionate about the work they do, which is why they are trying to work so hard on keeping fortnite alive (and succeeding, might i add), so they can avoid loosing another game. it may seem like they didn't try to save paragon, but sometimes somethings are just too far gone to save, so they try to save fortnite before it needs saving.
thanks for listening to my speech. i ad no intention of it getting this long. sorry for any long windedness. have nice day
