One of the biggest problems of gw2 I think is wasting rely good ideas by bad implementation or just drop them in game with no system around them to improve their effect, And one of them will be the commander tag.
The commander, the player who has that cool icon on top of his head that you can see even on the map, the one that every new player will look at as one of the elite of the game, the one that will show them the way!. all that means nothing now as every one who has 300 gold can just buy in the way even if he is an idiot who knows nothing about the game and the mechanics of it. how we can know if that person who put on the tag to lead people in an event missing raid or whatever is rely reliable to do so. why not put a system that implement the commander tag in an competitive environment and show people what is the rely capability of the commander's.
What if we have another window in game specifically for the commander tag system that let's say divide commander's to 4 divisions exp :"officer=>lieutenant=>commander=>general" and drop the cost of the tag to 50 gold and another 50 each time upgrade division and make upgrading to other division depending on an achievement. For exp to upgrade from officer to lieutenant you have to command party of 10 minimum in (5 protect event /5 collecting events/5 ...). and on each division we put more harder event like world bosses to meta's then raids and Strike Missions at the top divisions and make the tag looks slightly different like how the division logo change or upgrade in league of legends for example, the logo get a wing or something at the sides that get's bigger each division.
and make the divisions downgrade on level each 2 or 3 months so they have to re'upgrade their last division. and they get's a an outfit or some kind of cosmetic that only wearable if your in that division. then lastly make a people in the squad to be able to rate the commander after leaving the party after successful event with like =(commander like +1) or dislike =(commander like -1) and make a leaderboard of each top 100 in each divisions with most likes that's will be shown in the commander window. and lastly make the window have 2 section (pvp tag/pve tag) with the pvp tag have different mission involve wvw .
And by that in my point of view we have better'ich system that make player's more involving and push them to make squads and help each other's and make it easier to people to pick who to follow and rely on specially new player's . and have better gold sinker then that useless one time 300 gold .
