When Truth Arena season 6 was released, the Giant system was not very popular with gamers because of the disadvantages it brought.
However, in the current version, everything has completely changed when the Giant system tankers are becoming extremely strong.
First, we need to recall a bit about the meta of version 11.23b when the formations related to the Inventor are becoming extremely strong.
As a result, gamers are forced to find ways to counter this overwhelming control ability.
And then people realized that instead of spending too much resources to do the above, they could use a much simpler way, which is to put Giant units on the field.
In addition, with the popularity of Tahm Kench at the present time, the Giant system becomes even stronger.
In short, with the current meta that places a lot of emphasis on control ability, the Giant system is the most effective countermeasure.
