Chromie time only works and is relevant between 1-59, if you want to run all expansions, I suggest to enjoy the content using chromie time, once you hit 59 I would seek out the npc as I mentioned in my first reply to you and lock your experience bar, You can still quest and get the rewards, gold, armor, rep etc except experience. You will remain the level you locked to. Once you have finished with Chromie time, seek out the npc and remove the lock, resume your questing. You may need to run a few dungeons until you ding 60 to qualify for the Dragonflight questline.
Between 1 – 60 you can use Heirlooms if you have them and upgraded 5/5 or 3/3. 60 – 70 don’t worry so much about heirlooms, questing in dragonflight will give you good questing gear from quest rewards, npc rng drops etc. It all depends on your play style, dungeons also drop decent gear too, then there’s pvp and war mode, bfa > shadowlands > Dragonflight reward decent gear for war mode.
When you ding 60 proceed with Dragonflight.
**Note that soon as you hit 60 chromie time ends.**
Basically without chromie time, yes, you will be too powerful for the ‘old’ content, you one hit kill npc’s etc, it’s super annoying if its a quest where you are required to injure an npc down to ‘45% – 55% hp’ and use a quest item on the npc. A good work around would be to use Soft Foam Sword on the npc and quickly use quest item before auto attack triggers, however, the issue is that sometimes the toy bugs out and you can’t use it at all. This is where chromie time comes in to play. With this mode, the expansion you choose will be within your level range and the rewards and npc’s will also scale to your level.
