No its not insane, its easy.
Rank 6 Gladiator
Rank 7 Hero
Rank 4 Skillz
And the rest of whatever is
here
Legendary protector / hero / defender are easy, just finish every mission on NM and HM with masters rewards.
Legendary Vanquisher is easy but time consuming. I did it very slowly but gradually over 3 years.
Legendary skill hinter is easy.
Legendary Cartographer is a pain in the 4$$, but doable with texmod.
6 x eternal conquerors are easy, just complete all of the end game elite content one time.
Lucky / Unlucky only need to be rank 2 to count, easy to do during canthan new year.
Luxon / Kurzick only need to be rank 4 to count, easily doable during a double faction weekend.
And then its just reputation title grind, and also zaishen supporter which you can grind random arenas for or just farm and buy keys.
When the HoM calculator first came out I was already on 22 points. Within a week I was up to 35 points with minimal effort, and then slowly kept going up towards 50.
It's only 'insane' if you only just started playing the game within the last few months, if you've been playing 6 years ..... well really you have to be a complete noob like me to only have 49 HoM points and 22 titles
The HoM rewards / titles are nothing more than achievements to unlock while playing, like the ones you have on Steam. Over the full course that the game has been out for, it requires next to no effort, just logging in and playing towards unlocking those achievements. The only thing that stopped me from getting GWAMM was sheer boredom after 2 years of playing hardcore.
