Welcome! As a Long time Gw1 player since prophecies I really feel there are some systems that GW1 had that could be Viable in GW2. Down below are a few things that really GW2 could have to improve gaming experience.
Daily Bounties/Hunter/Challenges ect
In guild wars 1, We had Zaishen quests which was Missions/Bounty and Pvp. Upon completing these you would receive bronze Coins. Get enough bronze and convert it to silver and so forth for gold. If you stacked up these golds you could get Better rewards. I believe you could pick up the bounty per character and they were repeatable after completion until reset. Yes we have Guild missions and Dailies and Monthlies but lets be honest. Dailies take a few minutes-Monthly a day or so. Guild Missions only happen once a week (You get rewarded once a week.) and its maybe 2 hours ish?
I would really love to see this In Guild wars 2. Make some of these Instances so its not just Zerg/faceroll. A Slight change was to make this only repeatable x amount of times per character. However a good thing about this was if you had a bounty from Yesterday that you didn’t complete, you wouldn’t lose it upon reset AND you could still get another bounty(You could have upto 3-4 i think MAX) so you could do yesterdays and todays. I think this would make maps more Engaging, And yes it could be argued that it would just end up being a Zerg-Fest for things such as champions (Not like Frostmaw but like little champs).
Example:
Have daily Bounties/Tasks/Challenges/Hunt/ect-Go out and kill a specific champion in this Location. Or hunt several Champions in several map location. Some champions require an event to spawn.
Challenge Areas
There was a few of these in Guild wars 1 which i found rather fun and Rewarding. It would be like Defending horde waves for as long as possible or Kill x amount of horde waves in the Quickest time Possible. And of course, We could only have a party of 8. It was some what rewarding as we could kill mobs for drops and complete the challenge and be rewarded for it. There were several like Elona and Eotn had ones that gave you hero Armour tokens i guess, to give to a vendor for HoM Points once acquire it.
A well known one was the Defending Glint in Eye of the North. You would defend glint and kill waves off Destroyers and Boss’s. Get loot-And this loot you could turn into a vendor and get Gloves (Destroyer gloves for destroyer cores) and upon completion reward. (Yes this was also a well known farm spot for most part)
We could have this in Guild wars 2. Make it party size 5-10. Make it an Instance like a Mini raid or Dungeon and make it worth while. Give us drops from mobs, few champions, Puzzle rooms. Complete this Challenge before X amount of time and you get A reward. Complete it before Y amount of time and get A+B Reward ect.
So far, these are two things i really think would help give players something to do. Especially the whole bounty/Challenge thing. Most people log on, do dailies, odd few dungeons and log off. Thoughts and Suggestions on this?
