I agree with many of the reasons this revamp is needed, but it still needs a lot of work to both fix those problems and retain what people enjoy about the current system. From what I've seen so far:
Good
- Unlock all trees right away
- Spend points in multiple trees (somewhat replacing Twists)
- Attempts to make more trees viable for casters
Bad
- Builder/Spender mechanic - please no, for the love of Mystra. Kill it with silver fire!
- Loss of power for most of the ETR cycle
- Loss of flexibility (can no longer swap destinies and twists at will for free, 3 trees don't fully replace twists)
- The build towards a level cap increase (please see my past posts for why this is a bad idea)
How to fix the bad while retaining the proposed system:
Builders/SpendersThis feels like a complete 180 from the past few years - the original Epic Destinies had several abilities with charge up mechanics that caused problem so the devs replaced most of them with normal cool downs. Now they want to add back a similar mechanic that is more annoying with quick decay and forcing it on every destiny across the board? Just please no. The only way to "fix" it would be eliminate all decay so it functions like the old epic moments. But at that point you might as well skip to the end part where you replace them with normal cool downs anyway.
Loss of power with level gatingI understand the desire to smooth out power through the epic levels, but gating abilities so close to 30 is detrimental to anyone going through a 20->30 TR. As mentioned by others, if you were to actually mirror the level gating of enhancements translated from a 1-20 cycle to a 20-30 cycle it would look more like this:
Tier 1: Level 20, 0 AP
Tier 2: Level 20, 5 AP
Tier 3: Level 21, 10 AP
Tier 4: Level 22, 20 AP
Tier 5: Level 25, 30 AP (Level 26 numerically but the first couple heroic levels are so fast that considering 12 as the heroic halfway point makes more sense, thus Tier 5 should be at the epic halfway point)
Even with the above changes, it still has a feeling of taking power away so you can sell it back again later. Very icky.
Maybe as an alternative you can allow people to gain epic past lives at the lvl cap? I would rather gain "epic past life xp" at 1/10 the rate at lvl 30 than go through an epic TR.
Loss of flexibilityEven if all new destinies are fleshed out and balanced as well as possible, the new system would still be less flexible than before. As mentioned elsewhere, right now we can swap destinies and twists for free between quests. This is done frequently, even multiple times a day between raids with different needs. The fix to that is easy:
- Resetting destiny trees should be free
Twists are trickier - they are so maximally flexible that you would need to either:
- Retain twists as a mechanic - pull single abilities from any tree you can access
Or:
- Expand the number of destiny trees available at once - 6 to match enhancements would be good, but to match twist flexibility we would need access to all trees at once
The eventual level cap increaseThere is too much to say about this here, but I still think raising the level cap would be harmful to the game. Alternate advancement systems at lvl 30 could provide everything people want from a lvl cap increase without the drawbacks.
How about instead of dividing players up into smaller groups you expand the grouping options? Maybe adopt a City of Heroes style auto scaling for all characters and gear, such that anyone could group with anyone of any level with no penalty. Then the character level won't matter so much.
