As a HoDA veteran i can't keep comparing the HoDA tournaments to SWGOH ones.
How HoDA is different? It has "ladder rewards" given for achieving a certain number of points.
For example, some experience for 50 points, some gems for 100 points, some shards for 150 points, etc.
There are literaly about a hundred small rewards. And sometimes an insignificant yet nice character on the very top (around 5000 points).
So even if you are not planning to compete for top 10 its nice to finish the ladder and collect these rewards. Especialy if you are missing this character prize on the top.
