The change is effective in both divisions and aims to encourage better pitches for four-day cricket.
"It is a bit of a rubbish rule," Raine told BBC Radio Leicester. "Hopefully it doesn't last too long. I'm not sure why the rule has been brought in.
"It's against the spirit of cricket and against the rules of the game."
The rule change means that Foxes skipper Mark Cosgrove will have the chance to decide if his side will bowl first in their opening County Championship match of the season against Glamorgan in Cardiff on 17 April.
England's limited-overs captain Eoin Morgan has said the move may benefit the game long-term, allowing younger players to develop different skills on better quality pitches.
Raine argues that the toss had little bearing on any of Leicestershire's County Championship results last season.
"I don't think there were too many pitches last year where the toss did really affect the outcomes," he added.
"The two games we did win, we did bowl first but there are plenty of times where we bowled first and lost."

The 28-year-old world record holder equalled the Olympic record - set by Czech Roman Sebrle at Athens 2004 - by scoring 8,993 points in Rio.
France's Kevin Mayer took silver with 8,834, while Canada's Damian Warner secured bronze with 8,666.
"To win two Olympic golds in a row like Daley and Mathias is very special," said Eaton.
"One day, I'm going to have to meet Daley, shake his hand and thank him for giving me something to chase after.
"My throwing has been bad in the past, but I really got after the discus and shot here. Can I do three in a row? Maybe you should ask Daley."
Eaton was the overwhelming favourite to follow Thompson's achievement from 1980 and 84 and is the third multi-eventer, alongside American heptathlete Jackie Joyner-Kersee, to win back-to-back Olympic titles.
He has dominated the event since 2011, claiming back-to-back world titles and twice setting new world records along with his Olympic success.
No British athlete competed in the 10-discipline event.

Heavy rain in Glasgow has resulted in a waterlogged pitch at Thistle's Firhill Stadium.
Not date has yet been set for the rearranged fixture.
Thistle, who have won their last four games, also had a top-flight match against Motherwell called off due to rain on 5 December.
Scrapping the mandatory coin toss in county cricket is "against the spirit of the game", says Leicestershire all-rounder Ben Raine.
