Support gems need more tiers

After playing through the campaign multiple times, I feel that Support Gems need more tiers. Maybe this will be addressed over time as more are added, but right now, the system stagnates at certain levels:

- By the middle of Act 2, you're still receiving Tier I Support Gems, but there's a high chance you don’t need anything in that Tier. There should be more than three tiers of Supports, and they should start appearing earlier. This way, there would be more recommended options, and experimenting with them would be easier—especially for new players.

- When playing a new character, you can use Tier III Support Gems accumulated from a high-level character, starting with them right away. Perhaps they should have a minimum level requirement, similar to active skill gems, so the system feels more progressive even when starting fresh.
