Sorry for being a bad Abomination driver.

I had read the guide and watched the video before the raid but it was trickier than I thought. Some tips here for Abomination drivers, so that you won't repeat my mistakes again.
1. Don't move unnecessarily! You don't need to move to the green/orange ooze to slow them down. Skill 2 (the slow debuff) has a very long range. Only move when you need to stack on green ooze target, or move to eat a new slime pool.
2. Don't eat too slowly! You need to spam skill 1 (eat slime) when eating slime pool. Try to finish one slime pool completely before going on to the other pool, otherwise all the unfinish pool will grow in size gradually and eventually becomes overwhelming.
3. Don't eat too fast! Early on it is possible to consume all the slime pool if you eat too fast and doesn't let the pool to grow. This causes problem because you need to eat to gain energy for casting the slow debuff (50 energy is needed).
If only we can practice it before coming to the actually raid......

[edit] One more tips: abomination can die. Simply click the table again to get a new one.
