This garbage has gone on for months. There is absolutely no reason why Teebo should not already be fixed. This issue is significantly hindering game play for those that have built teams around this character.
It has been stated that stealth would need an entire rework to fix this character. That is a bunch of hogwash. There's a very simple fix to this situation:
Teebo has an ability that guarantees him stealth for 3 turns. This ability has a 5 turn cooldown. So for 3 out of 5 turns, Teebo is guaranteed to have stealth. For the remaining two turns, he has a 50% chance to gain stealth. So over time, he should be stealth for one out of two of those turns on average. This means that Teebo should most often have stealth for 4 out of every 5 turns. Raise the chance to gain stealth for Teebo to 80% and call it a bandaid.
Far too often, Teebo gains stealth via the guaranteed 3 turn ability and drops stealth THE VERY NEXT TURN. He then proceeds to not gain stealth at all over the next 3 turns. So he is going 4 out of 5 without stealth! This is completely unacceptable.
The fix is easy. The only reason not to have fixed it is because you are upset over the turn meter reduction component in raids. Get over it. Who cares if one person can solo the T7 raid? A one person guild would only be able to generate the coins for this raid once every 100 days. Furthermore, the overall loot drops do not decrease or increase based upon damage. Number one on the raid chart gets the same loot whether they do 10,000 damage or 10,000,000 damage.
The challenge to this game is the grind. Once you have made the investment in leveling, gear, stars and abilities (which often means you have invested cash as well), you should be able to enjoy what you have paid for. Not have a variance of millions in damage based upon bugs that aren't fixed and random number generator garbage. You want TM reduction to be less effective? Then make a raid with multiple targets so they can't all be controlled. You already removed the ability for TM reduction to affect the Rancor with the gate down. Fix this junk and let us play how we developed to play.
Give Teebo an 80+% chance to gain stealth on every single turn and call it a day. This can be done tomorrow. Stop making excuses.
