I'm not against this idea by any means, but the only reason I don't want this to happen is because I don't think it'll fix the current problem. Which is the fact that most of these aspects are unused in players loadouts and there still wouldn't be a reason to run them over the other ones that are incredibly strong. Sure they can just give a buff to these aspects like they did with Lightning Surge and a couple others, but I don't feel like some of these need them because they provide a strong ability that no one really considers because "why not just run what everyone else is running", they just need a small edge over the other options to consider running them like a fragment slot increase. Ascension has an argument to be ran over Lethal Current on Arc Hunter now because it has more fragment slots. Even on Prismatic, the most powerful aspects available to each character has 2 fragment slots and I think that's more than fair considering the power/survivability they provide. If the fragment slot cap was gone, everyone would probably continue to keep running the same 2 or 3 aspects and then they'd need to find another way make the underperforming aspects stronger by buffing/reworking them, but even then, have you seen anyone run Tempest Strike or Juggernaut even after the buffs they got? A buff can be hit or miss, but a fragment slot increase will always provide something to an aspect that isn't as strong and removing the cap would kind of take that away. The best example of this I can think of is Gunslinger, if the fragment cap was gone, no one would ever run On Your Mark and it would probably need a complete a rework, and considering the trend of Arc Titan rn, I think Touch of Thunder and Juggernaut would also never get touched and would need a rework/buff as well. I'm not saying these things would be bad, but think about whether or not they would even happen first considering recent events at Bungie, it would probably be easier to increase the fragment slots on an underperforming aspect and give it a small buff as opposed to increasing the fragment slots on every aspect and give the underperforming ones a complete rework. These are just my opinions obviously, if good reworks happened and every aspect had 3 slots, that would be awesome, but I don't think it's gonna happen anytime soon, I don't even think my original suggestion would happen anytime soon tbh. I am glad to see others that think that 4 fragment slots is super restrictive tho, I wasn't sure anyone really felt the same.

Never claimed it would fix anything, I was just sharing my thoughts on the matter, you were saying every subclass but prismatic is restrictive with fragment slots so I simply just siad what I felt was right. Some aspects simply just aren't used cause they're either only usefull in the small part of the game(pvp) or just flat out pointless to use. For example I have mained shadebinder for 4 years now and even if frost pulse or glacial harvest got 3 slots i still wouldn't use them because of theire functionality, that being siad I fully agree they need adjustments on the side of the game were they are less used. After all if an aspect does the closest thing to nothing or is just flat out boring than why use it? At least thats what I think I'm more of a what I have fun with over meta/ majority used.

I know you didn't claim it would fix anything, was just stating what I think would happen if the fragment cap went away with no other changes. I hear you on Shadebinder tho, I only used Glacial Harvest for elemental shards builds before Lightfall changed the mods system and not much else other than that, and Frost Pulse never, it could use a buff, maybe add a functionality that decreases class ability cooldown when you have Frost Armor so you could use it more often, idk. I'm not saying that the fragment increase should be the only thing changed about the aspects I suggested. but I'm not gonna sit here and think of buffs and nerfs that probably aren't gonna happen for every single thing I find underpowered, sometimes the better solution to making something more desirable to a player is an easy one, like a fragment slot increase, it definitely worked on Ascension, I saw no one running it on arc and sometimes on Prismatic last season and now the most common combination of aspects I see on arc hunters are Flow State + Ascension. That's mainly why I thought of this post was because of the Ascension changes and how well it ended up working for both arc and prismatic.
