possibly make it a gw1 primer for those that never played the first one as well maybe.
cant say i’ve had any issues with the endurance refill, not even mid dodge that causes most skill interrupts, used it often to get 4 dodges off back to back.
not sure if it stops it but have you been using the haste skill?

At level 30 theres 3 zones for content your level, genderran fields, lornars pass and fields of ruin.
That said you can head to any below your level and gain xp and loot as same rate.
