1) The status bombs, Voltaic Tempest, Stagger Storm, Shivermist Buster, Ash of Agnie, Venom Veiler took like half a sec longer to inflict status on players in pvp, and monster in pve. Sometimes the monster and players can walk through it without getting inflicted at all.
Several bomber buddies are experiencing the same problem.
2) After I killed the Jelly, the spike that it was trying to use was still in progress and it will still pops up and attack you, which is very weird.
This is something that was pointed out when they first made the change to slimes. Back then they used to do their spike attack a lot more often so bombing them became almost impossible because you could push them back or kill them and their spikes would still come up. The "solution" was to reduce the frequency of their spike attack so it was still annoying but it was annoying less frequently.
This will never get fixed as I think it's an issue with the way the attack is coded.
