I chanced upon this thread and thought I’d share some information that might help. I’m a current T500 Role Queue player with multiple friends in the T500 as well and I can confirm that as far as I know, you can no longer get the T500 icons for being in T500 in OW2. Everybody I know who has the regular orange T500 icons (including myself) had them from OW1, and it seems that the T500 icons are no longer earnable rewards in OW2 (at least in Role Queue) and have been replaced with the Competitive Titles instead.
The only communication I’ve found from Blizzard regarding this is in this post where they say:
" Competitive Rewards
Competitive season will be aligned with our overall seasonal schedule, including the Battle Pass. We’re removing the commemorative sprays and icons players earned each season, including the top 500 sprays and icons. We’re introducing new limited Competitive titles for your name card that you can earn as you climb the ranks. These titles will be a way to show off to other players how high you climbed in a season. You can only earn these titles at the end of the current Competitive season and only use them in the season following."
& similarly in this forum post they mention:
| Highest Skill Tier | Rewards |
|---|---|
| Bronze | 65 CP |
| Silver | 125 CP |
| Gold | 250 CP |
| Platinum | 500 CP |
| Diamond | 750 CP + Diamond Challenger Title |
| Master | 1200 CP + Master Challenger Title |
| Grandmaster | 1750 CP + Grand Master Challenger Title |
TOP 500 LEADERBOARDS
The best of the best players compete across five separate Top 500 Leaderboards. Within Role Queue, one for each role, along with an additional combined average leaderboard. The combined Role Queue Top 500 Leaderboard will be based on the player’s average skill rating across all three roles. To be eligible for a role-specific leaderboard, players must complete at least 25 games in that role. To qualify for the combined Top 500 Leaderboard, players must be eligible for all three role-specific leaderboards. Open Queue will have its own Leaderboard that will require at least 50 games played within the game mode for qualification. At the end of the season, players who earn a spot within the Top 500 players for any of these leaderboards on their platform and region will receive an exclusive title instead of their rank.
In both posts they mention the T500 players only receiving competitive titles and it does seem indeed that it is now impossible to get the old T500 icons in OW2. Hope this information helps!
