To summarize my previous posts in here:
Swordman class is fine as it is.
Swordman class has a wide variety of solo builds that rank among the best ingame.
Swordman class also has a wide variety of tank/support builds, which usually include at least a single rank of Peltasta.
For players who like to solo swordman class is a treasure trove of various builds. Which is why a lot of players go for the former kind of swordman build.
For people who want to commit themselves to make a group based build, classes like wizard and cleric seem the obvious choices, which is why there are not a lot of players going for the latter kind of swordman build.
Now TOS sadly by the way it is designed does not really encourage group play(outside of instanced dungeons) in the early (1-150) levels. This goes even more for builds capable of soloing well - why would they bother with a group if they are more effective alone. - solo builds profit
Once you get to the later levels though, party play becomes more and more common. Now of course, by the same logic solo players were playing alone before, parties prefer to take people who can actually contribute. - party builds profit
The problem, which this thread is trying to discuss is in my opinion only percieved because the perspective is screwed.
The problem is not that all Swordmen need to pick Peltasta to stay relevant in later party play.
Rather players who play solo a lot will play Swordmen, usually builds without Peltasta. Because Swordmen are great at soloing - especially the builds without Peltasta.
Those players now hit the wall of “oh damn party play is awesome now, but i couldn’t contribute much to a party if my life depended on it because I specialized my build to be a strong solo character”. Honestly? You get what you signed up for. You played an awesome solo build that is still awesome at soloing. It is just that grouping up gets better than soloing. You want in on that? Make a build that can contribute. Very much unlike op presents this, the variety of such builds is great, even in Swordman class.
TL;DR;
You were not forced into anything. You committed to a build that was awesome for 200 levels and now gets less awesome. In reaction you look down on the other players that had a hard time getting to the point where they are relevant and call them op and demand a rework so you can keep being awesome forever? Don’t be like that. You’re unreasonable.
