I started this again back in early February. Have been taking my time and just using one character. Currently at level CP136. Haven't bothered about gear at all, just change up every so often as the stuff I am currently wearing gets too far out leveled. Waiting until I hit CP 160 before concentrating on proper gear. Going to finish the main quest and start doing some of the public dungeons when hit that CP160 mark.
I am also levelling up my crafting skills. All of them. I have Blacksmithing at level 50, Clothier at level 50. All the other crafting skills are between 40 and 48, except for Jewelry which is only at 25.
Oh, I haven't assigned any of my champion points yet. Still undecided about what way I want my character to go. Currently two handed and bow, both using mainly using mainly DPS skills. I still have my respec scolls. When I hit CP160, am thinking of going for a tank build using one handed and shield. I know that will mean levelling up some new trait lines, but that shouldn't take too long!!
On champion points, you can always reallocate them but there is a gold cost. Not sure if your aware, but can also respec all your skills and points at the shrines in the main cities also in case your worried about burning that respec scroll. Once again a gold cost, but not too massive.
On a tank, may find it easier to set up an alternate character. Neat thing with alternate charters as soon as you hit level 50, they will get all the champion points your, so in your case CP136 also and and XP they earn will contribute to increasing the champion points. Only reason I say that, is tank generally has much less DPS and can make overwrold content / missions a chore IMO and stats will change significantly from a DPS setup.
