It's the stats system they worry about I assume...
Above the character issues in a solo/1v1 setting, downing 20 players in solo is much easier for a good player than what it is in a squad game and then also a knockdown generally leads to a kill which the developers stress about when thinking about solo modes because one of Apex's main driving forces is stats and bragging rights............BUT.............The game is getting to a stage where an option like Lone Wolf needs to be integrated otherwise my gut tells me a lot of people will just get fed up and this is far too good a game for simple complications/features to be fixed/withheld inevitably causing more of a CON EFFECT than a PRO...
When weighing the PROS vs * of a solo mode from all angles of this game and taking the player base's acceptance as a whole of such a mode on top of the effect on credibility of stats/achievement due to a solo mode it complicates the issue a lot but, it also doesn't take a rocket scientist to put aspects in place to counter such problematic areas:
To introduce a solo mode compromises will have to be made and whenever compromises are thrown on the table developers fear repercussions and negative backlashes springing up...
My view is a solo mode can not be introduced if it contributes to stats? And/Or unlocking badges (like 20 kills per single game) or longest winning streak counter or damage done...
If everyone is happy with a compromised introduction/test period I can't see why a game mode like solo should not be introduced?
Rather than adding to the physical stats give players solo badges carrying stats? Like MOST KILLS IN SOLO or SOLO HIGHEST DAMAGE DONE and SOLO GAMES WON I mean the possibilities are endless?
BUT SIMPLY NOT INTEGRATING A MODE DUE TO A FEAR OF THE UNKNOWN is not the right course to take?
I would like solo personally because I know I'll be good at it...And I'm sick of that annoying French guy on his mic in every second game trying to delegate (playing a Wraith) even though his stats are minuscule to yours?
I suggest Respawn integrating a basic 3 question pop up box once a week which is mandatory asking 3 game related questions and players simply tick yes or no. A fail safe way of making the game what players want it to be. Annoying but ultimately effective.
BOX ONE:
Would you like a solo mode in APEX yes no
Would you like auto aim removed from pc yes no
Would you like wall-running integrated (Titan-style) yes no
