Half tempted not to post this 'cause it's fun to troll the enemy team when they're losing badly enough for me to hang around their spawn, but I'm just too honest for that.

You can shoot sun shard projectiles into the enemy spawn on Furnace and Reactor, and possibly other maps (doesn't work on Forest and Necropolis, iirc) by placing the bomb directly against the barrier. The two angled projectiles will impact the barrier, but the perpendicular one will shoot inside the spawn area and damage/kill enemy players inside.

It is rather hilarious watching them take alchemer pot shots at me, thinking they're safe from my shards...

And while you're fixing the shards, can you please make the projectiles not impact on yourself and friendly teammates? Thanks.
