The new announcer sounds a bit underwhelming for more exciting action that takes place.
When someone gets a pentakill the announcement seems very anticlimactic and monotone. I was wondering if anyone else was of the opinion it needs some spicing up for more exciting game achievements. I'm mainly speaking about kill streaks and major team-wide objectives. Acing the enemy team, securing Baron Nashor/Dragon would be a few examples. I think it would be an awesome change if it had the same excitement and thrill as the old one if it changed tone to fit the occasion. This is just my opinion.
Edit: Sorry I didn't realize it was temporary. I would totally buy this new announcer if it was made into a sound pack and tweaked a bit. Please Rito...
