Let's face it, nobody respects battle mentors. Getting 1500 glorified brownie points and completing 1000 instanced dungeons not only does not require any skill playing tank, healer, or DPS roles but teaches nothing about the game's battle mechanics to the point where you can adequately give advice to fledgling new players trying to learn their way through the game. You know it. We all know it. The thing is that the battle mentor status could be much better and be respected within the community.
To that end, the requirements should change and all players given mentor status should be removed until they reach new requirements.
I would propose that in addition to the already existing requirements, there is an added requirement that you must complete 50 current Savage instances. An example of a current savage instance would be only P1s-P4s counting towards this number until the release of patch 6.2, then only P5s-P8s would count. This would exclude min-iLvl runs of older savage fights and extreme trials which in most cases are too easy. 50 would be the ideal number given that within on patch cycle assuming they adhere to the 4-month time schedule you would be able to clear 48 savage instances provided you are obtaining a full tier clear by week 4 and continue to farm until the end of the patch. It requires dedicated play but is still more than reasonable to do for a player that actually understands how to play the game within an 8-month time period (i.e. 2 patches). In addition to this, mentors should be required to complete 50 savage instances per raid tier in order to maintain mentor status. This is important in order to ensure mentors are a bit up to date regarding job balance and dungeon changes that occur during patch changes and to deter plays to buy their way through this requirement. "bUt wHaT If YoU qUiT tHeN cOmE BaCk?" you shouldn't be a mentor. Added to this, a mentor that is reported for harassment should be barred from ever gaining mentor status ever again.
Adding a harder requirement to being a battle mentor would put some meaning into having the status, instead of some person who ran ARR dungeons on healers and kept telling people "Hey guys I'm only 100 coms away from mentor status, make sure you give me your coms at the end of the dungeon UwU TY". With a stronger meaning to the status, we could then actually point to battle mentors as people who have enough game knowledge to explain to players basic mechanics like the type of mitigation, when to use single target rotations vs AoE, lining up buffs and CDs, and other basic yet nuanced in formation. This isn't to make mentors shilling advice like "go look a guide on RDM rotation" or pushing people to look at Akh Morning or the Balance but to ensure that players can know that a battle mentor actually knows basic stuff about the game and can provide more in-depth information.
