- Pennants now work for any game that's part of a tournament.

VISUALS

- Player's chosen team pennant will display in the fountain area.

DOTA 2 BOTS
- Added Lich bot.
- Added Death Prophet bot.
- Added Viper bot.
- Bots will now select heroes their teammates have suggested in the hero picker.
- Increased the radius and strength of fountain avoidance.
- Tuned the strength of bots desire to place a ward, they should be somewhat more cautious about it now.
- Bots now wait 15 seconds after hero-picking to spring into action. This gives players the opportunity to buy their own couriers, if they want.
- Bots will no longer try to TP out of a fight if they're currently visible to the enemy team.
- Bots now try to path through FoWed areas when retreating.
- Bots now pay attention to multiple pings, and will use them to strengthen their desire to attack a hero, defend a lane, or push a lane.
- Bots that are disabled due to missing players on the opposing team are now also invulnerable so they cannot be farmed.
- Supports will now defer last-hitting to non-supports in their lane.
- Bots on easier difficulty levels will now be worse at retreating out of a gank.
- Fixed bug with the avoidance of Dark Seer's wall (only half the wall was being avoided).
- Slightly increased sticktoitiveness of bots overall, but moreso for medium and easy bots.
- Made Tiny bot less likely to Avalanche when retreating (so it's harder to harass him into using all his mana).
