Tier 4 Basic Cats require far too many Shards
I remember way back in the day when I went to Rank up a Champ and realised I needed a Few Catalysts that I hadn't paid much attention to, Tier 4 Basic Catalysts, so I checked my inventory and saw that I had 1 and needed 2 more I checked how many shards were needed and for a moment it registered as 3600 cause Tier 3 is 2800 but than I realised it was 36,000 almost 13x more shards needed that are much harder to obtain, 18,060 is a more reasonable number and it follows the math of the Rising Shard Requirements, T1 is 300, T2 is 650, T3 is 2800, T4 should therefore be 18,060
300x2.16=650
650×4.30=2800
2800x6.45=18,060
Instead it jumps from 4.3x to 12.8x more shards, now I realise there are champs out there who have used alot of T4 Basic Cats, the developers could take the amount of T4s you have used break that number down to shards and than reward each player 4 T4s on a weekly basis til they even out, that way your cats dont time out in your stash and everyone gets a piece of the pie. It wouldnt be the first time they've awarded every single player for content already completed. T4 Basics have been a point of Contention for a long time and it's a simple change to show appreciation for players that have made them Rich by giving them their Time and Money
