The idea of Quests should be changed . Just see the example of arena. There are many quests there that are so general and easy that they will automatically get completed no matter what match you play. In SF3, you need to defeat a guy upside down and 10% health remaining to complete a certain set of quests . That's .... boring and irritating. Especially for end game players who don't see any value in doing these quests ( we've been playing long since 8 years and we're done with the same repeated quests ).
Also redo the rewards for quests .
Make some weapon Achievements too so that once we achieve it we unlock something cool , like a skin or perk or special move or anything but **Shadow Energy Orbs**
For example : in Delta Force mobile we get a special skin by doing a certain quest - like killing 100 players with a specific gun to unlock a special skin ( Exclusive ) . You can do the same with sets / weapons - the same logic can be applied to unlock some exclusive special moves or perks. However this value to obtain should be realistic and reasonable ( not like 1000 kills in 30 days to win - No ) .
Also please note that people do not enjoy grind . They enjoy challenge . Both are different. Challenge is something you can win but is little harder or challenging to achieve . Doesn't require playing 3 hours every day. That's grind . Most fans here maybe have grown up into adulthood and are busy with work. So try to make things practicable for our part of the community - thank you !
