I like how you so often come into a thread, and rehash something we've already gone over, starting straight from the beginning, and always with a poor take. You don't bother reading what anyone is saying, and you just double and triple down on whatever you showed up with. Why participate in a discussion if you don't discuss anything, if all you want to do is repeat your first post?
1) "Hero pulling" odds are clearly listed IN THE GAME and required to follow those odds for Raid to continue to operate
2) Glyphs only tell you what they can roll between. There are no listed odds. If a glyph says 1-3, then it is possible to roll a 1, 2, or 3. If I was to guess, those percentages look like a 50% chance to roll 1, a 30% chance to roll a 2, and a 20% chance to roll a 3.
You see, for something to be random it doesn't have to be equally weighted. For example, you are playing a lottery game, and you select 5 out of 100 numbers: 20, 31, 44, 67, and 92. You now have a 5/100 chance on the first pull that one of your numbers is selected. Does the fact that 95 numbers aren't yours and only 5 are make it not random anymore? It does not in the slightest. You are literally asserting that for something to be random it must equally weighted. You want the chance one of your five numbers are selected to be 50%, and one of the 95 other numbers selected to also be 50%.
Let's break it down into something that is more related to the discussion than your initial post about how your Glyph RNG proves Plarium is manipulating the shard rates....
Random does not mean equal. Not everything in your life is a coin flip. You are not equally as likely to be hit by a meteor today as you are to have a nice sunshiny meteor free day. That is a crazy random cosmic occurrence, being hit by a meteor. But you would argue it must be 50/50 to be random. In fact, if we compare you having a good day, you being hit by a meteor or you being struck by lightning, you would say it needs be 33/33/33 or else it is MANIPULATION.
