This. I loved getting extra skill points as rewards in BL1. Would have loved to see that return in 3.
There are advantages to more frequent but smaller cap raises (less of an XP grind to reach the new cap at each increment, old cap weapons still being at least serviceable) when the increment is only 3-4 levels, but it still pushes lots of players away from the game. Many hate even the thought of the farming grind because they believe they’ll just to have to re-start the process again before a full set of final gear can even be acquired.
The severe loot- and anointment-pool pollution problems, plus the lack of a modern crafting/upgrading/re-rolling system also contribute to this issue. This creates the feeling that the drop system is designed more to troll the player than anything else. Those who want to legitimately farm their gear often feel like the effort is pointless.
This problem can’t be disentangled from the level-cap raises because it is the combination of the two problems that turns players off.
The idea of more points as a reward for completing content also incentivizes actually doing something with TVHM if, say, the reward for completing DLC4 was 2-3 extra skill points per playthrough.
