Is act 5 exploration worth it or not?

Hi everyone, i just wanted to know from summoners who have explored act 5 a 100% whether I should go for it or not. The reason being it is resource consuming and with the EQ exploration and me trying to do an intial clear of polar opposites V3 and arena grinding, alliance war/quest, I'm finding it hard to explore act 5. I'm at 64% on act 5 exploration but feeling kinda stuck at the following paths namely rage, spiked armor and power reserve. As always any feedback is greatly appreciated and have a great day.

You basically want to view yourself in one of two modes. Champs are free, champs are not free.
When champs are free: Start with the most difficult portion of the monthly event you intend to complete (chapter 3 UC for example). As soon as that is done, immediately switch to whatever permanent content you are working on for the rest of the month.
When champs are not free: Go back to the less difficult monthly content that does not require your top champs (ch.1 and 2 UC, master, heroic, etc.)
It's about always utilizing the time you have with your top champs. You may already be doing this, but just wanted say something in case it's helpful at all.
